I'm starting to find the naive techno-optimism here annoying. If you don't have capital or can do something else you will be homeless.
I'm not convinced software developers will be replaced - probably less will be needed and the exact work will be transformed a bit, but an expert human still has to be in the loop, otherwise all you get is a bunch of nonsense.
Nonetheless, it may very well transform society and we will have to adapt to it.
Having a lot of specifics about a programming environment memorized for example used to be the difference between building something in a few hours and a week, but now is pretty unimportant. Same with being able to do some quick data wrangling on the command line. LLMs are also good at parsing a lot of code or even binary format quickly and explaining how it works. That used to be a skill. Knowing a toolbox of technologies to use is needed less. Et cetera.
They haven't come for the meat of what makes a good engineer yet. For example, the systems-level interfacing with external needs and solving those pragmatically is still hard. But the tide is rising.
Of course the question that is left unanswered is how the economy will work there's no one left with purchasing power. But I guess the answer to this is, the same way it works now in any developing country without much of a middle class.
Most of us will probably need to shift to security. While you can probably build AI specifically to make things more secure, that implies it could also attack things as well, so it ends up being a cat-and-mouse game that adjusts to what options are available.
My guess is the opposite: they'll throw 5–10x more work at developers and expect 10x more output, while the marginal cost is basically just a Claude subscription per dev.
The resources to learn how to construct software are already free. However learning requires effort, which made learning to build software an opportunity to climb the ladder and build a better life through skill. This is democratization.
Now the skill needed to build software is starting to approach zero. However as you say you can throw money at an AI corporation to get some amount of software built. So the differentiator is capital, which can buy software rather cheaply. The dependency on skill is lessened greatly and software is becoming worthless, so another avenue to escape poverty through skill closes.
