Maintaining and rewriting existing shit is quite well paying though, and also something that AI seems to struggle with. (Funnily enough, AI seems to struggles even more with refactoring vibecoded projects than with refactoring human-written apps. What that says about the quality of the vibe coded code I don't know.)
That's why sw devs salaries went up like crazy in our time and not in 1980.
But what new tech will we have, that will push the SW dev market demand up like internet connected PCs and smartphones did? All I see is stagnation in the near future, just maintaining or rewriting the existing shit that we have, not expanding into new markets.
