The end state, I think, is that everyone who needs small software to manage a todo list or synchronize files, or whatever "normal" people do, will end up with bespoke personalized software written by their own AI. SWEs will be reduced to working on only the big corporate projects.
The overwhelming trend in commercial software these past few decades has been hyper-aggressive anti-customization, anti-personalization, anti-user. Commercial software has been reduced to one single happy path and if that doesn't suit your needs, then fuck off. No one is making commercial software for everyday people. Even open source is trending away from everyday users.
Soon, regular everyday people who simply need some software to solve a problem the way they want it solved will have the ability to do so. In the bast majority of those cases, the quality and correctness of said software really doesn't matter. What matters is that it's personalized, free, and isn't an invasive surveillance/advertisement platform.
