There will be exceptions that do become long lived projects of course. probably even the same amount there were before. But there's going to be a few orders of magnitude more throwaways so on average any new piece of code is going to be a throwaway
Do you not see the problems that arise here? Are we losing our accumulated engineering best practice knowledge? Standardized, common, highly reviewed subsystems provide working engineering know-how and accumulated lessons learned. Not even the best AI systems can keep that many considerations in mind when re-spinning code.
If this is your default assumption, I hope I never have to rely on code you generate.
