Note that I'm not claiming to have $10M, that was a hypothetical number for the purpose of the question.
That said, sure, I have certainly entertained the idea of retiring and working on open source, particularly on days when work is frustrating or overwhelming.
But if the goal is "recreate Sandstorm", I do believe my current work on Cloudflare OS[0] is much more likely to succeed at that than anything I could reasonably accomplish independently.
More broadly, at the moment it feels like my position at Cloudflare puts me in the middle of something really important. There isn't anywhere else where I would have more influence over the AI revolution.
