I actually think that AI might be closer to Web 2.0 than blockchain. Where I see it's biggest potential though isn't in the stuff most people do everyday, but in specialized applications. I see some of the uses in stuff like medical research and find the potential there to be wild. In alot of ways, it's sort of a revolution in how we think about doing computing. We're still really early on it, so its hard to know just where it takes us. Even on the more mundane stuff, it really does help programmers be alot more productive (though it's hardly a replacement for talented programmers). Which is a huge for helping us build the next generation of tech.

There's alot of stuff they say is obsolete but really isn't. For example, in my day job, I'm an analog IC design engineer. The most advanced process I work on is sort of 90nm (but not really). The previous silicon process I worked on was basically a 0.5um process. Ask most people and that's all stupidly obsolete - should have died out in the 90s or something. But I work on power products. Power is analog, not digital. We may have some digital stuff, to be sure, but what we fundamentally do is analog. And you can't use 5nm processes to deal with "high" voltages - that's all on "old", "obsolete" silicon processes. Oh and you know what we power with all this? Among many other things, those fancy AI chips. So yeah, alot of these transitions do obsolete stuff, but there's often still important niches in older technologies. I mean you still have people learning COBOL so they can program mainframes for banks.
