YC has become an educational brand as powerful as some top schools
Sure, no school will prepare you for the amount of hype and grift the tech industry has to offer quite like reading Hacker News does.
As an educational institution I'd rate them somewhere between Prager U and UnIversity of Phoenix.
If they have a full room to themselves, a DC might let them fuck around without supervision. There's no way I would let them into the structural/electrical bits without seeing his signature under the mother of all responsibility waivers, though.
After that, if this was just a regular asshole I'd hope their fuckaround trip goes without a major incident both to save myself from a lot of trouble and out of common decency towards a fellow human. This particular asshole would really be testing the limits of the latter.
