Exactly. Which means the risk level to founders is high. Because it is a roulette wheel where the VCs are the house, and the founders are the gamblers. With TechStars vs. YC being akin to the difference of the wheel having one zero or two. Founders are still gambling... even if YC gives better odds than others.
Again, VC has it place, as does YC. I'm not saying nobody should do it - I'm saying they should do it as a fully informed decision.
