It seems like you’ve enjoyed this recent trip to San Francisco? What would it take to get you to move here?

Gwern 

Yeah, it is mostly just money stopping me at this point. I probably should bite the bullet and move anyway. But I'm a miser at heart and I hate thinking of how many months of writing runway I'd have to give up for each month in San Francisco. 

If someone wanted to give me, I don’t know, $50–100K/year to move to SF and continue writing full-time like I do now, I'd take it in a heartbeat.

Market resolves to yes if Gwern moves to the bay area anytime before July 1st. Maybe someone else can make a market on whether he'd stay.
