Coding is just going to be asking for a result and manually testing it, no real thought about what code has been generated, and no human should ever need to look at or review it. Even some versioned tarball on s3 will do for the storage.
So, really, who cares about what they do when their entire business model (and Github's) is speedrunning becoming obsolete?
Basically, the future of tools like github is a platform for manual testing, where the AI proposes a change and you can experiment with the UI and attach notes for the next iteration. The whole idea of coders carefully reviewing the output of LLMs is insane, it'd be like carefully poring over the output of GCC; we've made lines of code so cheap and skill-free that there's no point in these platforms that treat code like it's important to view.
