I think the key thing here is he's talking about "the person who made the previous world's largest slice of cake". In other words, if I were working on a new programming language (just as an example), and could go hire Anders Hejlsberg as a consultant, well, that -is- going to be a mega cheat code. The amount of experience he'd bring to bear to even a 30 minute call would be insane. He would save me months or even years in mistakes and bad directions, and lead me straight to the core of whatever I wanted to do. That's the thing - he's not talking about hiring a generic "cake consultant". With that in mind, it'd be much easier to find those people - you'd know them by their achievements.
