Why you shouldn't join Y Combinator

Thank you for this material! It was nice to read about another side of the moon. I have already shared it with a group of people, who discussed how to apply to YC the other day

Basically he is arguing; successful people were merely Lucky”. I disagree! There are people who have multiple unicorns. (Jason Cohen).

I agree that YC is optimising their slave labour. Where I disagree is “ YC wants you to pick an idea that has market pull (or the potential for it), and to then dig a hole in the same spot until you reach the boiling magma”.
I insist this is the best way to find a gem. By hammering on a problem consistently from various angles.
