WEBVTT 00:00.000 --> 00:09.560 So, many thanks. So, here is our first, let's say, real speaker for this afternoon, 00:09.560 --> 00:16.520 that's Steve Goodwin with rewriting the original Elisa and chat box. So, Steve, you don't 00:16.520 --> 00:21.720 have any time for Biona, because you have 20 minutes starting right now. 00:22.720 --> 00:24.720 Thank you. Thank you all. 00:25.720 --> 00:29.720 As this part of the slide, Steve, and the back part of the slide, there's my bit of a key. 00:29.720 --> 00:33.720 If we've all turned up the correct demo, this is going to be a talk about Elisa. 00:33.720 --> 00:36.720 It was a chat port that was rented about 60 years ago. 00:36.720 --> 00:41.720 It means exactly 60 years ago on January 1st, 1966. 00:41.720 --> 00:43.720 I'm going to talk about some of the history of Elisa. 00:43.720 --> 00:48.720 I'm going to talk about the way that I read both Elisa and live by line into JavaScript. 00:49.720 --> 00:52.720 Because JavaScript is the one true language. 00:54.720 --> 00:57.720 Okay, I'm going to cast the microphone. 00:57.720 --> 01:01.720 And then the reflections of what I thought are to do it all this crap. 01:01.720 --> 01:03.720 But before all this, who am I? 01:03.720 --> 01:06.720 One of my sons to earn a place on this stage. 01:06.720 --> 01:08.720 Okay, someone might know that. 01:08.720 --> 01:10.720 No, no, no, no. 01:12.720 --> 01:16.720 What I'm going to do in my, and one of my down to earn a place on this stage. 01:16.720 --> 01:20.720 Or this slide should be called the ego slide. 01:20.720 --> 01:22.720 This is where the speaker brags about themselves for 10 minutes. 01:22.720 --> 01:26.720 While everyone tries and work out if they can still get to the other dev room. 01:26.720 --> 01:30.720 Well, I'm a general purpose computer geek, totally unemployable, 01:30.720 --> 01:34.720 because all of my skills are based in computers that are quite literally dust. 01:34.720 --> 01:38.720 If this computer was made more than 40 years ago, I don't want to know. 01:38.720 --> 01:41.720 I wrote a book about El computers not so long ago. 01:41.720 --> 01:44.720 I've done various things that open source conferences like this. 01:44.720 --> 01:49.720 This is my 28th talk at first time over the last 26 years that I've been here. 01:49.720 --> 01:52.720 So some of you might have seen me before. 01:52.720 --> 01:55.720 Has anyone seen me performed before? 01:55.720 --> 01:58.720 And you came back. 01:58.720 --> 01:59.720 Oh, boy. 01:59.720 --> 02:01.720 So all of this is not important. 02:01.720 --> 02:03.720 There's nothing on this slide which is important. 02:03.720 --> 02:06.720 I am not a professional retro developer. 02:06.720 --> 02:10.720 I'm just a general purpose geek who happens to like playing with stuff. 02:10.720 --> 02:14.720 Which is a long-winded way of saying, if I can do this, anyone can. 02:14.720 --> 02:16.720 So what are we talking about? 02:16.720 --> 02:18.720 Well, this is Elizer. 02:18.720 --> 02:19.720 Elizer was a chatbot. 02:19.720 --> 02:20.720 You would ask it questions. 02:20.720 --> 02:21.720 You would type in your question. 02:21.720 --> 02:23.720 It would give you an answer. 02:23.720 --> 02:25.720 It's named for Elizer doodle. 02:25.720 --> 02:28.720 A character from millions from Bernard Shaw's play. 02:28.720 --> 02:30.720 Back from 1913. 02:30.720 --> 02:31.720 1913, yes. 02:31.720 --> 02:32.720 It's retro group. 02:32.720 --> 02:33.720 1913. 02:33.720 --> 02:34.720 Get over it. 02:34.720 --> 02:37.720 And she was actually born in listen growth. 02:37.720 --> 02:40.720 The character was born in listen growth in London. 02:40.720 --> 02:42.720 That's me in listen growth last month. 02:42.720 --> 02:47.720 And the character in the play was taught how to speak plopper like. 02:47.720 --> 02:51.720 She was a woman of low social classes. 02:51.720 --> 02:53.720 Victoria's standards here. 02:53.720 --> 02:56.720 And she was taught how to speak well and educated. 02:56.720 --> 02:59.720 So that men of the day would find her attractive. 02:59.720 --> 03:03.720 And the whole play is about her becoming this other woman. 03:03.720 --> 03:07.720 So Elizer was named for her because it was essentially. 03:07.720 --> 03:12.720 We're going to make this computer seem like it's real. 03:12.720 --> 03:14.720 And it kind of worked. 03:14.720 --> 03:17.720 So these are the sort of things that you will probably read about. 03:17.720 --> 03:22.720 If you go online and you find someone's blog about Elizer or you ask chat TV. 03:22.720 --> 03:24.720 T about Elizer. 03:24.720 --> 03:26.720 This is the sort of thing it will tell you. 03:26.720 --> 03:28.720 It's all wrong. 03:28.720 --> 03:30.720 Almost all of it is wrong. 03:30.720 --> 03:32.720 It was written by Joseph Eisenbaum. 03:32.720 --> 03:34.720 Well, and it was in 1966. 03:34.720 --> 03:36.720 He wrote it in 65. 03:36.720 --> 03:39.720 But it was published in 1966 in January. 03:39.720 --> 03:43.720 In the computational linguistics magazine at the ACM. 03:43.720 --> 03:46.720 This program was not written in Lisp. 03:46.720 --> 03:49.720 It was written in part mad slip. 03:49.720 --> 03:53.720 Yes, that's the actual name of the language mad. 03:53.720 --> 03:55.720 The Michigan Algorithm decoder. 03:55.720 --> 03:59.720 And slip, which is symmetric list processor. 03:59.720 --> 04:02.720 They didn't make it easy for us to neither. 04:02.720 --> 04:08.720 And some of these code was optimized in Fortran assembly programming. 04:08.720 --> 04:14.720 Fortran assembly program or FAP or FAP for short. 04:14.720 --> 04:19.720 The code of conduct does not allow me to put that on the slides. 04:19.720 --> 04:21.720 So Elizer is not a program. 04:21.720 --> 04:23.720 It's two programs. 04:23.720 --> 04:26.720 There is the Elizer code, which is written in mad slip. 04:26.720 --> 04:28.720 This actually does the work. 04:28.720 --> 04:30.720 But it doesn't do actually anything at all. 04:30.720 --> 04:32.720 Unless you give it a script. 04:32.720 --> 04:34.720 And the script was called Doctor. 04:34.720 --> 04:36.720 And the Doctor script is actually what happens when you say, 04:36.720 --> 04:38.720 Oh, I'm feeling quite happy. 04:38.720 --> 04:39.720 Why are you feeling happy? 04:39.720 --> 04:41.720 That's doing all the work. 04:41.720 --> 04:43.720 Not Elizer. 04:43.720 --> 04:45.720 Well, so we got. 04:45.720 --> 04:47.720 It was published in the ACM. 04:47.720 --> 04:49.720 But only the Doctor script was published. 04:49.720 --> 04:51.720 Only this bit. 04:51.720 --> 04:54.720 If Eisenbaum gave a good description of how it worked, 04:54.720 --> 04:56.720 but didn't actually show his code. 04:56.720 --> 04:58.720 I'm that open source conference. 04:58.720 --> 05:01.720 And we can't show his code. 05:01.720 --> 05:06.720 Also, it's not advanced at all. 05:06.720 --> 05:09.720 It is basically pattern matching. 05:09.720 --> 05:13.720 And it isn't very complex pattern matching at that. 05:13.720 --> 05:16.720 If you say something like, I am sad. 05:16.720 --> 05:19.720 It just responds with, why are you sad? 05:19.720 --> 05:21.720 There's no intelligence there. 05:21.720 --> 05:22.720 I mean, granted. 05:22.720 --> 05:25.720 It's a better relationship than when I had a few years ago. 05:25.720 --> 05:27.720 But it's still stupid. 05:27.720 --> 05:28.720 It is not advanced. 05:28.720 --> 05:30.720 And it's not the four one to LLMs. 05:30.720 --> 05:33.720 Everyone thought, oh, this is just like an LLM. 05:33.720 --> 05:34.720 No. 05:34.720 --> 05:36.720 LLMs have chewed up everything. 05:36.720 --> 05:38.720 Every copyrighted thing mostly. 05:38.720 --> 05:41.720 And chewed it up and spits it out. 05:41.720 --> 05:43.720 This has no memory. 05:43.720 --> 05:45.720 The only way this responds is with the question. 05:45.720 --> 05:47.720 You just gave it. 05:47.720 --> 05:51.720 So there's no real processing there beyond what you give it. 05:51.720 --> 05:54.720 And this is one of the things that chewing always said about AI. 05:54.720 --> 05:57.720 It's a behaviorist approach to AI. 05:57.720 --> 06:01.720 If you think this thing is intelligent, you escape it intelligence. 06:01.720 --> 06:03.720 Therefore, it is intelligent. 06:03.720 --> 06:04.720 Spoiler alert. 06:04.720 --> 06:07.720 It is not intelligent. 06:07.720 --> 06:10.720 And also, everyone says it can pass the chewing test. 06:10.720 --> 06:12.720 It didn't pass the chewing test. 06:12.720 --> 06:14.720 It couldn't pass the chewing test. 06:14.720 --> 06:17.720 But there is the favorite story about the secretary. 06:17.720 --> 06:20.720 Visonbaum's secretary was using this program. 06:20.720 --> 06:22.720 It was trying it out. 06:22.720 --> 06:24.720 And she said, Joseph, go away. 06:24.720 --> 06:26.720 I'm talking to the computer. 06:26.720 --> 06:28.720 She believed it was real. 06:28.720 --> 06:31.720 She thought there was a genuine sort of human being inside the computer. 06:31.720 --> 06:33.720 There wasn't. 06:33.720 --> 06:36.720 But what a good magic trick that is. 06:36.720 --> 06:39.720 So we're going to do that. 06:39.720 --> 06:41.720 Okay. 06:41.720 --> 06:42.720 Okay. 06:42.720 --> 06:43.720 You people have got my palm. 06:43.720 --> 06:44.720 Thank you for that. 06:44.720 --> 06:46.720 I've got three fans on the audience. 06:46.720 --> 06:51.720 So the whole way that it lies a work is basically decomposing what you've typed in. 06:51.720 --> 06:56.720 And then reassembling the thing you've just typed in. 06:56.720 --> 06:58.720 See, I do have time for beer. 06:58.720 --> 07:00.720 There is always time for beer. 07:00.720 --> 07:02.720 So, what does it do? 07:02.720 --> 07:06.720 These are some of the rules in the doctor script. 07:06.720 --> 07:11.720 If you see the word me, if you've typed that in, the computer will change it to you. 07:11.720 --> 07:15.720 If you type in the word r, it will change it to am. 07:15.720 --> 07:16.720 And so on. 07:16.720 --> 07:18.720 If it has the word u, it changes to i. 07:18.720 --> 07:20.720 And then it does this match. 07:20.720 --> 07:25.720 So that is zero or more words followed by the word i. 07:25.720 --> 07:29.720 With zero or more words followed by the word u and zero or words. 07:29.720 --> 07:34.720 It will reply with, why do you think whatever happens to be in place free? 07:34.720 --> 07:36.720 Blah, blah, blah. 07:36.720 --> 07:39.720 It's basically a regular expression, isn't it? 07:40.720 --> 07:45.720 So, if you type in something like, you are always correcting me. 07:45.720 --> 07:47.720 Well, what's it going to do? 07:47.720 --> 07:48.720 Meet to you? 07:48.720 --> 07:49.720 Yep. 07:49.720 --> 07:50.720 It sees the word me. 07:50.720 --> 07:51.720 Changes it to you. 07:51.720 --> 07:54.720 Sees the word r, changes it to am. 07:54.720 --> 07:57.720 Sees the word i, and u changes it to i. 07:57.720 --> 07:59.720 I am always correcting you. 07:59.720 --> 08:03.720 And then it reassembles that to there. 08:03.720 --> 08:05.720 I am always correcting you replace it. 08:05.720 --> 08:08.720 Why do you think I am always correcting you? 08:09.720 --> 08:11.720 That almost sounds real. 08:11.720 --> 08:14.720 That sounds like an actual person. 08:14.720 --> 08:16.720 And this is why it was created. 08:16.720 --> 08:20.720 This was the idea of a luxury and psychiatrist. 08:20.720 --> 08:23.720 Their whole thing was, i feel sad. 08:23.720 --> 08:24.720 Why do you feel sad? 08:24.720 --> 08:28.720 And at the end of the session, you are quite literally giving them the answer. 08:28.720 --> 08:30.720 They don't have to do anything. 08:30.720 --> 08:32.720 They just repeat it back to you. 08:32.720 --> 08:34.720 And that's all it was doing. 08:34.720 --> 08:35.720 But as we said, we're chewing. 08:35.720 --> 08:36.720 It's behaviorist. 08:36.720 --> 08:41.720 It just feels real because you ascribe it intelligence. 08:41.720 --> 08:44.720 So this example is that regular expression. 08:44.720 --> 08:50.720 So I transformed this code. 08:50.720 --> 08:51.720 Did you want to do that? 08:51.720 --> 08:54.720 That does work by the way. 08:54.720 --> 08:56.720 And yes, I did write it. 08:56.720 --> 09:01.720 And yes, I am that sad. 09:01.720 --> 09:07.720 So this regular expression is just one of the 100 different things you could do in the 09:07.720 --> 09:08.720 Doctor script. 09:08.720 --> 09:10.720 I decided to break it down. 09:10.720 --> 09:13.720 NAD is a programming language that no one's used for 60 years. 09:13.720 --> 09:18.720 So I had to find the old IBM documents which have been luckily scanned in by someone 09:18.720 --> 09:20.720 and stuck onto PDFs. 09:20.720 --> 09:23.720 I had to then build this for emulation of this. 09:23.720 --> 09:28.720 Because the first idea is, well, why don't I just emulate the whole system. 09:28.720 --> 09:30.720 But I've only done that. 09:30.720 --> 09:32.720 There's a project online and the links are in the slides at the end. 09:32.720 --> 09:34.720 I'll show you them. 09:34.720 --> 09:39.720 There is the entire original platform in the original operating system where you can run the original 09:39.720 --> 09:41.720 Eliza under emulation. 09:41.720 --> 09:43.720 It's quite effective. 09:43.720 --> 09:44.720 I didn't want to do that. 09:44.720 --> 09:48.720 I don't learn anything much by just copying something. 09:48.720 --> 09:49.720 I learned by doing. 09:49.720 --> 09:53.720 So I rewrote all this mad code into JavaScript. 09:53.720 --> 09:55.720 I know what some of you are thinking. 09:55.720 --> 09:57.720 One mad language to another. 09:57.720 --> 09:58.720 It's fine. 09:59.720 --> 10:05.720 So I wrote this entire parser that would handle mad code and then interpret into JavaScript. 10:05.720 --> 10:09.720 It also handles the slip component and the fat component. 10:09.720 --> 10:11.720 And I broke it down line by line. 10:11.720 --> 10:15.720 So this is an example of what mad looks like. 10:15.720 --> 10:17.720 Perfectly ordinary. 10:17.720 --> 10:20.720 So I went through it just line by line. 10:20.720 --> 10:22.720 I created some classes. 10:22.720 --> 10:24.720 I did all the normal settings you do. 10:24.720 --> 10:26.720 What does that do? 10:26.720 --> 10:30.720 Well, it looks like it says right zero and three zero. 10:30.720 --> 10:32.720 No, it doesn't. 10:32.720 --> 10:38.720 It's whenever IT equals zero and FR equals zero. 10:38.720 --> 10:40.720 Equals. 10:40.720 --> 10:43.720 Whenever variable name. 10:43.720 --> 10:45.720 And. 10:45.720 --> 10:47.720 Oh boy. 10:51.720 --> 10:53.720 You read that sort of code for a while. 10:53.720 --> 10:54.720 You do that. 10:54.720 --> 10:59.720 You use the papers to force them. 10:59.720 --> 11:01.720 And that's what it looks like. 11:01.720 --> 11:04.720 It's like a normal code. 11:04.720 --> 11:05.720 There are many years ago. 11:05.720 --> 11:09.720 I wrote a book and it was translated into Chinese. 11:09.720 --> 11:14.720 And as happens, I gave a copy to my parents and my mother looked at the book and she goes, 11:14.720 --> 11:19.720 I do not understand this because while you don't understand the computer books, 11:19.720 --> 11:21.720 of an English, you're certainly not going to 11:21.720 --> 11:23.720 understand it when they're in Chinese. 11:23.720 --> 11:25.720 And when I read my own book in Chinese, 11:25.720 --> 11:27.720 I suddenly realized what she meant. 11:27.720 --> 11:30.720 I couldn't understand my own book either. 11:30.720 --> 11:32.720 And I can't understand that. 11:32.720 --> 11:35.720 But after a while, you just get used to it. 11:35.720 --> 11:39.720 So you read the line, you interpret what it means, 11:39.720 --> 11:42.720 you rewrite it in JavaScript and you keep going. 11:42.720 --> 11:45.720 Because this is just mad code, this is all it is. 11:46.720 --> 11:48.720 One slight issue. 11:48.720 --> 11:51.720 The variables in mad can be lists. 11:51.720 --> 11:54.720 Lists are not a native data structure in JavaScript. 11:54.720 --> 11:57.720 So you've got to do something there. 11:57.720 --> 12:00.720 You've got whole series of processing code. 12:00.720 --> 12:03.720 This processing stuff here, that's all list-based. 12:03.720 --> 12:05.720 So you've got to write your own JavaScript 12:05.720 --> 12:06.720 wrappers for each of those things. 12:06.720 --> 12:08.720 And it uses go-to. 12:08.720 --> 12:11.720 Who has used go-to recently? 12:11.720 --> 12:14.720 How do you have jobs? 12:14.720 --> 12:19.720 I have not used to go-to in years. 12:19.720 --> 12:24.720 So I had to find a way of using go-to in JavaScript. 12:24.720 --> 12:26.720 And it wasn't very clever in the end. 12:26.720 --> 12:28.720 I just, you know, fact around a bit. 12:28.720 --> 12:32.720 But I created types for all these list type of things, 12:32.720 --> 12:34.720 which don't exist in JavaScript. 12:34.720 --> 12:36.720 Some nice little functions there. 12:36.720 --> 12:38.720 The code's not the best. 12:38.720 --> 12:39.720 It works. 12:39.720 --> 12:41.720 I have an interpreter. 12:41.720 --> 12:45.720 So every time I want to get a value out, I use my little method. 12:45.720 --> 12:48.720 If I want to reference the variable, it just creates one. 12:48.720 --> 12:51.720 Because there's no declaration of variables in mad. 12:51.720 --> 12:53.720 It just says, if you've used the variable, 12:53.720 --> 12:55.720 it will suddenly come into existence. 12:55.720 --> 12:58.720 So you don't have any sort of initialization. 12:58.720 --> 13:02.720 You just have to handle it yourself in these wrappers. 13:02.720 --> 13:05.720 And mad code, as we said, goes from this to this. 13:05.720 --> 13:07.720 So instead of writing this directly, 13:07.720 --> 13:10.720 I reference the interpreter and process it. 13:11.720 --> 13:15.720 That does mean that if I want to manipulate these values in any way, 13:15.720 --> 13:17.720 such as in this example, 13:17.720 --> 13:21.720 I have to take it out of the interpreter's store, 13:21.720 --> 13:23.720 manipulate it in straight JavaScript, 13:23.720 --> 13:26.720 and then assign it back into the interpreter. 13:26.720 --> 13:28.720 It's a bit of a path, 13:28.720 --> 13:31.720 but it means that everything can be handled exactly the same. 13:31.720 --> 13:33.720 Regardless of what you're doing, 13:33.720 --> 13:36.720 whether it's an integer as it is in this case, 13:36.720 --> 13:38.720 a string or a list. 13:39.720 --> 13:43.720 And for go-to, that this TO thing is transferred to, 13:43.720 --> 13:44.720 that is go-to. 13:45.720 --> 13:48.720 What I did is I created a whole series of functions, 13:48.720 --> 13:50.720 and every function you could jump to. 13:50.720 --> 13:52.720 You'd have a function when it got to the end, 13:52.720 --> 13:54.720 or you returned from the function, it would say, 13:54.720 --> 13:56.720 this is the function I want you to call next. 13:56.720 --> 14:01.720 So essentially, you've got 100 functions called line 10, line 20, line 30. 14:01.720 --> 14:04.720 And that's how I fake to go-to. 14:04.720 --> 14:06.720 Pretty much like that. 14:07.720 --> 14:10.720 I do not recommend faking go-to. 14:10.720 --> 14:14.720 Go-to was removed from programming languages for a reason. 14:14.720 --> 14:16.720 Keep it that way. 14:16.720 --> 14:18.720 Don't do this. 14:18.720 --> 14:21.720 Unfortunately, when you're processing code from 60 years ago, 14:21.720 --> 14:23.720 you don't have any choice. 14:23.720 --> 14:27.720 So this is basically all I do. 14:27.720 --> 14:29.720 There is a trick in JavaScript, 14:29.720 --> 14:31.720 you can do where you can put labels, 14:31.720 --> 14:33.720 and you can continue to labels, 14:33.720 --> 14:35.720 and they pretend to be go-to's. 14:35.720 --> 14:36.720 Don't do that. 14:36.720 --> 14:38.720 But it was another way of just getting around the problem 14:38.720 --> 14:40.720 of having no go-to in JavaScript. 14:40.720 --> 14:43.720 So when you've got to that point, 14:43.720 --> 14:46.720 you just go through and you just grind out all the code. 14:46.720 --> 14:48.720 You see something like this, 14:48.720 --> 14:50.720 and you now recognize it, 14:50.720 --> 14:53.720 process it, and that's what it becomes in JavaScript. 14:53.720 --> 14:55.720 Line by line, 14:55.720 --> 14:58.720 and you never know it's going to work until you've done the whole program. 14:58.720 --> 15:01.720 There is no, I'll test a little bit of it. 15:01.720 --> 15:04.720 You've got to get all the way through before you suddenly realize, 15:04.720 --> 15:06.720 oh, I've got a bug. 15:06.720 --> 15:08.720 And because there's no real way of testing this, 15:08.720 --> 15:10.720 you just have to push through with it. 15:10.720 --> 15:12.720 There's also some fun things in there. 15:12.720 --> 15:14.720 As a consequence, I did do this cheat sheet, 15:14.720 --> 15:16.720 so these are on the slides at the end. 15:16.720 --> 15:18.720 You'll see the references. 15:18.720 --> 15:20.720 These things are fun. 15:20.720 --> 15:22.720 These are referencing a list, 15:22.720 --> 15:24.720 and there's pop top and things like that. 15:24.720 --> 15:26.720 There are two functions in here, 15:26.720 --> 15:27.720 which are really annoying. 15:27.720 --> 15:29.720 One is called empty list, 15:29.720 --> 15:32.720 and the other is called list empty. 15:33.720 --> 15:35.720 One of them empties the list. 15:35.720 --> 15:38.720 The other says is the list empty. 15:40.720 --> 15:44.720 How many times do you think I'm going to get that wrong? 15:44.720 --> 15:46.720 So after grinding this stuff, 15:46.720 --> 15:47.720 I've got a nice cheat sheet, 15:47.720 --> 15:49.720 so if you want to learn how to code in mad, 15:49.720 --> 15:51.720 you can. 15:51.720 --> 15:54.720 This is some of the slip functions that I've now created. 15:54.720 --> 15:56.720 Those are your empties and your sequels. 15:56.720 --> 15:57.720 These are all good fun. 15:57.720 --> 15:59.720 And I probably should do a demo, 15:59.720 --> 16:01.720 but the reality is that demo is actually not that fun. 16:01.720 --> 16:03.720 And there's only five minutes left, 16:03.720 --> 16:04.720 so I'm not going to. 16:04.720 --> 16:06.720 My reflections on doing all of this 16:06.720 --> 16:08.720 is basically, 16:08.720 --> 16:10.720 it's weird. 16:10.720 --> 16:11.720 When you see a computer 16:11.720 --> 16:14.720 that you know was programmed 60 years ago, 16:14.720 --> 16:16.720 but it occasionally feels a little bit human. 16:16.720 --> 16:17.720 You suddenly feel, 16:17.720 --> 16:18.720 oh, 16:18.720 --> 16:20.720 now I see why other people 16:20.720 --> 16:22.720 think that AI is magical. 16:22.720 --> 16:23.720 It isn't. 16:23.720 --> 16:24.720 AI is just sassy, 16:24.720 --> 16:25.720 autocorrect. 16:25.720 --> 16:28.720 But people seem to like it. 16:28.720 --> 16:30.720 As they do with Eliza, 16:30.720 --> 16:32.720 it actually does seem to work. 16:32.720 --> 16:34.720 And because at its simplest form, 16:34.720 --> 16:36.720 Eliza is a name. 16:36.720 --> 16:38.720 And that might seem an obvious point. 16:38.720 --> 16:40.720 But I'm not saying it again anyway. 16:40.720 --> 16:42.720 Eliza is a name. 16:42.720 --> 16:43.720 When you say, 16:43.720 --> 16:44.720 hey Eliza, 16:44.720 --> 16:45.720 I'm feeling sad. 16:45.720 --> 16:47.720 It feels like you're talking to a person. 16:47.720 --> 16:48.720 It's not, 16:48.720 --> 16:49.720 hey copilot. 16:49.720 --> 16:51.720 Write some really bad code for me. 16:51.720 --> 16:53.720 You're talking to a person at this point. 16:53.720 --> 16:54.720 The person has a name. 16:54.720 --> 16:56.720 It feels like there's an individual there. 16:56.720 --> 16:59.720 And I think that really gives it a lot of sway. 16:59.720 --> 17:02.720 It's the same as if you go to a hypnotist. 17:02.720 --> 17:07.720 The hypnotist's first job is to make you believe they are hypnotist. 17:07.720 --> 17:08.720 Because at that point, 17:08.720 --> 17:09.720 their job's done. 17:09.720 --> 17:10.720 You believe them, 17:10.720 --> 17:12.720 so you will get hypnotized. 17:12.720 --> 17:13.720 You talk to this as a person. 17:13.720 --> 17:14.720 You're thinking, 17:14.720 --> 17:16.720 like, this really is a person. 17:16.720 --> 17:17.720 It's AI, 17:17.720 --> 17:18.720 and of port, and of port. 17:18.720 --> 17:19.720 Okay. 17:19.720 --> 17:20.720 No. 17:20.720 --> 17:22.720 Not doing it. 17:22.720 --> 17:24.720 AI, 17:24.720 --> 17:25.720 and of port. 17:25.720 --> 17:27.720 Oh, 17:28.720 --> 17:30.720 and of port. 17:30.720 --> 17:31.720 And of port. 17:31.720 --> 17:32.720 And of port. 17:32.720 --> 17:33.720 And of port. 17:33.720 --> 17:35.720 That's what I said. 17:35.720 --> 17:37.720 Well done. 17:37.720 --> 17:39.720 And we just described it. 17:39.720 --> 17:41.720 This value of being an intelligent thing. 17:41.720 --> 17:43.720 And we know it isn't. 17:43.720 --> 17:46.720 So this code that was written 60 years ago. 17:46.720 --> 17:47.720 It's now available. 17:47.720 --> 17:48.720 It's on the GitHub. 17:48.720 --> 17:49.720 The slides coming up. 17:49.720 --> 17:52.720 You've got the original code with all the T. 17:52.720 --> 17:54.720 High funds and all the other kind of crap. 17:54.720 --> 17:55.720 You've got a pretty version. 17:55.720 --> 17:57.720 You've got an expanded version. 17:57.720 --> 17:58.720 You've got a cobbented version. 17:58.720 --> 18:00.720 And the JavaScript version. 18:00.720 --> 18:04.720 There's only 2003 lines in that Eliza code. 18:04.720 --> 18:06.720 That's the mad slip code. 18:06.720 --> 18:11.720 Then there's only 233 lines in the dot to script that runs. 18:11.720 --> 18:15.720 My JavaScript code is 2558 lines. 18:15.720 --> 18:18.720 But you know what I do in my code? 18:18.720 --> 18:20.720 I add comments. 18:20.720 --> 18:22.720 Gotcha. 18:22.720 --> 18:24.720 So the new other resources. 18:25.720 --> 18:27.720 This is all the stuff. 18:27.720 --> 18:28.720 Grab them. 18:28.720 --> 18:30.720 It's not a finished project. 18:30.720 --> 18:32.720 It kind of works now. 18:32.720 --> 18:34.720 It is a working progress. 18:34.720 --> 18:36.720 So grab all the links. 18:36.720 --> 18:37.720 Have fun with it. 18:37.720 --> 18:39.720 Mess around. 18:39.720 --> 18:42.720 I don't care. 18:42.720 --> 18:43.720 And that's me. 18:43.720 --> 18:44.720 Oh, sorry. 18:44.720 --> 18:45.720 I should update my scorecard. 18:45.720 --> 18:46.720 There we go. 18:46.720 --> 18:47.720 29th talk given. 18:47.720 --> 18:48.720 Thank you. 18:48.720 --> 18:49.720 Good night. 18:50.720 --> 18:51.720 Thank you. 18:51.720 --> 18:52.720 Thank you. 18:52.720 --> 18:53.720 Thank you. 18:53.720 --> 18:54.720 Thank you. 18:54.720 --> 18:55.720 Thank you. 18:55.720 --> 18:57.720 Thank you. 18:57.720 --> 18:58.720 Thank you. 18:58.720 --> 18:59.720 Thank you.
