There's definitely a few phases of Github, feature and popularity wise.

   1. Free hosting with decent UX
   2. Social features
   3. Lifecycle automation features

In this vein, it doing new stuff with AI isn't out of keeping with its development path, but I do think they need to pick a lane and decide if they want to boost professional developer productivity or be a platform for vibe coding.

And probably, if the latter, fork that off into a different platform with a new name. (Microsoft loves naming things! Call it 'Codespaces 365 Live!')
