Self-driving trucks are not here, nor are they coming anytime very soon, but driver assistance systems really have advanced meaningfully since 2012. They will continue to do so, to the point where I imagine driving without them will feel pretty alien. I feel much the same way about AI; it will change everything, but we need to be thinking of that change on thirty or fifty year timescales. 2030 won't feel so different to 2025.
The same goes for self-driving cars. It's a exponential, hockey-stick curve that at some point crosses the level of human ability. There is nothing "linear" about it and your suggestion of parallels to former experience is wildly misguided.
People fail to notice, most jobs are less complicated than math and programming. The "obstacles" there are of the kind of "we always did it this way", but that's no real "moat"?
The bubble regarding the big AI firms may well collapse, but the assumption, that was somehow improving the situation is far-fetched.
People automated out of a job will either compete with those in other jobs or be dependent on support. Either way, salaries will fall across the board and prices rise. At an ever accelerating pace.
You're probably right about the rest. I don't understand how prices can rise when salaries fall. Who's paying the higher prices?
Now if all these resources were instead put into actually improving things, then we'd be far better of, unfortunately, for all the intelligence the people behind these things possess, they seem to be stuck in the "lets do the same but faster" mindset.
So far I see that my own work as a programmer has changed radically, and it is far more productive. I still have a lot of work, but I really don't know how this will play out.
All the 'easy' to automate things have been automated already. A lot of things that were not automated is because there are small bits of problematic things that made it not worth while or the loss slightly too high. AI vision systems solve a lot of this.
