I would do it for free, just to answer the question of what does a genius of his caliber have in his garage? Probably the same stuff most people do, but it would still be interesting.
I don’t think the point was about having a clean space, it was in response to a question along the lines of: when do you think we will achieve AGI?
Trust me, I’m a genius of his caliber. Want to clean my garage? You free next week?
