chunk 0 · 0:23–0:51 · 82 words · 419 chars
0:23 OK, hi.
0:25 All right, I've got a lot to talk about, so I'm going to launch right into it here.
0:29 So SWIX says that you only get to make one point at every talk, one key takeaway.
0:35 And so I figured I'd just lead with that.
0:37 My key point is personal AI code gen breaks traditional cloud infrastructure.
0:43 And to clarify what I mean about that, the word personal here is doing a lot of work.
0:49 It's load-bearing, as Claude would say.
0:53 My point is that if we want to see this future where everyone has personal apps and can personalize the apps that they run, the infrastructure we're using today for software in general is not the right thing and we need something completely different.
chunk 1 · 1:09–1:47 · 98 words · 506 chars
1:09 So to explain what I mean.
1:13 Think about the way that software is produced and distributed today.
1:18 You have a developer in an ivory tower who builds an app and then sends it down to the people, the users who use the app, and many of them are happy with it, but some of them are not.
1:31 Some of them say, this app needs some additional features for my use case.
1:37 And so they go to the developer and they say, oh, great developer, will you please grant my feature request?
chunk 2 · 1:43–2:27 · 128 words · 734 chars
1:43 Your app is literally unusable without it.
1:47 And so then the developer's representative, the product manager, takes these feature requests and files them into JIRA where they are never seen again.
1:57 But sometimes, sometimes the product manager sees the feature request and says, ah, you know, I want that too.
2:02 And then that feature request goes onto the roadmap and the developer works on it.
2:09 And the developer is implementing all these features, features that, you know, each one is only used by a small subset of users.
chunk 3 · 2:17–2:56 · 119 words · 617 chars
2:17 And each one is adding all these if statements, their code, and making things messy.
2:22 And they don't like it because the code base is becoming a mess.
2:25 And each of these features are really kind of boring to implement.
2:28 And the developer says, ah, I know what I need to do.
2:32 We need a rewrite.
2:36 We need a new architecture that has a plug-in system.
2:40 And then every one of these features can be a plugin and it can be nice and clean and easy to build and the core can stay clean.
chunk 4 · 2:48–3:25 · 112 words · 608 chars
2:48 And so the developer goes off and starts working on the new architecture with the plugin system.
2:53 And there are still feature requests coming in.
2:57 And the developer says, well, we can't do those features yet because we need the plugin system.
3:03 This will be so much easier once we have the plugin system.
3:06 And if we do it now, we're just delaying that and we'll just have to redo it later anyway.
3:12 The years go by, and the new architecture is not ready yet, and none of the features are being implemented, and people are saying, what are they doing?
chunk 5 · 3:21–4:01 · 99 words · 520 chars
3:21 This developer has given up their product, and everybody is sad.
3:27 So, AI seems to present a new alternative to this.
3:34 What if the developer could
3:38 create their app, the first version of their app, give it to the users, and the users, if they need a new feature, could say, I could ask their AI agent to write that feature just for them, add it to the app.
chunk 6 · 3:52–4:36 · 111 words · 617 chars
3:52 Then everyone gets the features they need, no one is bogged down in everyone else's features, and the developer gets to keep the core app nice and clean and beautiful.
4:03 But there's a problem with this, which is that none of the infrastructure we build software on today is remotely designed for this.
4:13 You've got Apple and Google for the past 15 years gatekeeping their systems to the point where there's five companies that can build mobile apps now because everyone else has been banned.
chunk 7 · 4:28–5:06 · 122 words · 633 chars
4:28 And it's almost easier in the United States to buy a gun than it is to get access to your own phone to install unsigned software.
4:36 You go to Google and you say, I want to install unsigned software.
4:38 And now they're going to say, oh, whoa, hold on, buddy.
4:43 You seem upset.
4:44 You should go home and think about this.
4:47 If you still want that unsigned software in 24 hours, then you can come back and talk to us.
4:54 Fortunately, we have a workaround for all of that, which is the web.
chunk 8 · 4:58–5:38 · 107 words · 570 chars
4:58 On the web, everyone can build whatever they want, and it turns out it's fine.
5:02 It's not the security disaster that Apple and Google keep telling us would happen.
5:07 So you can build whatever you want on the web, but there's a different problem on the web, which is that for the past 25 years of cloud architecture, we've been running in the wrong direction.
5:22 When you distribute a web app,
5:25 you run it on your own server.
