GitHub is publicly destroying itself in a desperate attempt to realize Microsoft's AI dreams, and as its main competitor your response is... to do the same?
Rather than going for a "Humans first, robot assistants welcome" approach which promises to deliver things like stability, reliability, trustworthiness, and human connections, they decide to go all-out on firing the humans and letting bots handle things like code review while explicitly shifting the existing human-first company values towards making the remaining humans responsible for the bot's mistakes.
They could've chosen to market themselves as the sane save haven for the GitHub exodus. Instead they choose to go down in history like Google abolishing "Don't be evil". But hey, I bet chanting "AI! AI! AI!" (albeit quite late to the game) will deliver a very solid lukewarm increase in shareholder value!
