Not necessarily -- it makes sense.

He realizes that a startup won't magically succeed by being a part of the right group or having the right connections. It still takes extremely hard work, undying dedication to users, timing, etc... YC is only one cog in the wheel, and plenty of startups actually succeed without them -- which might seem disillusioning to some, especially those that hang around these boards too often.

I believe that's what he's getting at, anyhow.
