I harbor some hope that the (sad) fall of human SWEs will at least be accompanied by language defragmentation. We don't need 38 systems languages once human taste is mostly out of the picture.
Programming languages were always designed as an abstraction to allow humans to more easily instruct a computer than by writing binary or assembly. If humans write natural language and don't check the generated code, there's no reason to take the hit of generating C, JS, etc that still has to be compiled and/or interpreted.
Forcing LLMs to do a shitty job of what a compiler can do deterministically is not a good approach IMO.
I think if changes will happen in this direction it will be around formal verification, it's more difficult to trust LLM generated code if you aren't completely brainroted on press releases, and traditionally formal verification was seen as more effort than it's worth, but a tool that's great that generating insane amounts of text is quite well suited to formally verifying code, and assuming you can figure out how to make the specification readable to people, you just don't (in theory) need to ever look at the code or the proof, even if it might be helpful to anyways in practice. I'm quite excited the future of software might be fully unhackable software being the standard, with hacking becoming something that's talked about as a brief criminal fad in the beginning of the 21st century, like how you might hear about coin clipping from before fiat currency.
