In a world where you could download the brain of any living person into your own, who would you choose? 

Assume you'd have all their knowledge and experience partitioned and available for recall

Munger is an obvious choice, but for whatever reason, I'm thinkin Ray from Ray's candy store. He immigrated from Iran back in the day and setup shop in the east village. Nice guy, tons of stories & likely wisdom

But if a dead person - I'd say Wayne Thiebaud 🍰
