It's crazy to me that apple would put one guy on a project this important. At my company (another faang), I would have the ceo asking me for updates and roadmaps and everything. I know that stuff slows me down, but even without that, I don't think I could ever do something like this... I feel like I do when I watch guitar youtubers, just terrible
I hope you were at least compensated like a team of 20 engineers :P
