Is that what YC has observed?

My theory is that people are looking for people to start a company with ASAP, rather than 4-5 years in the future after they've worked together for a while.

But I could be wrong.

Sure there are people like that but the thing is you don't have to. No one is dictating you that you must start a company within certain time frame.
