Comparing to twitter is astute, as there are some analysis that point to it being mostly bots in 2025.

I can see the same happening for GitHub, in fact it seems to be actively trying to move in that direction: a platform for AI agents to host code, to review code, with little to no human activity.

Just like everyone who didn’t want to deal with bots left twitter, they will soon leave GitHub for similar reasons. I’m sure there is a future for GitHub as the code hosting platform for agents but it should be no surprise then when real people like Mitchell and the rest of us jump ship.
