That is the doom side. However AI has found and fixed a lot of security issues. I have personally used AI to improve my code speed, AI can analyze complex algorithms and figure out how to make them much faster in ways I can do as a developer, but it's a lot of work that I typically wouldn't do. Even just writing various targeted benchmarks to see where the problems really are in my code is something I can do, but would be so tedious I often would not bother. I can tell AI to do it and it will write those.

Only time will tell which version of the future we end up with. It could be good or bad and we will have to see.

In terms of runtime performance of applications, AI is a net win. You can easily remove abstractions like Electron, React, various libraries. Just let the AI write more code. You can even do the unthinkable and write desktop native again.
