The article makes exactly the right realization: Y Combinator is heading in the direction of scholasticism. Aren't you just reading into it what you want to read? I don't think that was the point of the article at all. Anyway, I think that school-like institutions for entrepreneurship with a formal process that you need to go though are destined to fail. They go against everything that entrepreneurship stands for. As…
At least it will be obvious when that happens since the startups will start failing.
Quite a few YC startups have already failed to build solid, growing businesses. Most startups do, after all. The good news is that former YC founders generally find other work, sometimes immediately via a talent acquisition of their former YC company. In other words, they cash in on their credentials, some of which obviously come from having been through YC.
So this "problem" of people seeking credentials by applying to YC has evidently been around for years by now. Fortunately, it's a feature, not a bug. At least until the day that YC starts accepting bribes, or selling spots in YC classes to the highest bidder.
As for folks like the OP's friend, who appears to be applying to YC not because he even wants to try to build a company but because he wants to collect a shiny gold star on his resume: He's as welcome to apply as anyone else. The question is whether or not he will be accepted.
