Just in case you thought Yud's attitude towards minors, sex, and substance use was worse than average for a Rationalist, the NYT asked around (archive):
Parties featuring psychedelic drugs and sharing of sexual partners are common, the people said. One house threw lavish events for the A.I. community so often that its owner claimed more than $200,000 of damage, including for a rodent infestation.
...
The (Genesis) house (in San Francisco) quickly became a hub for events. Eric Zhu, 19, a tech entrepreneur, said he used to sneak into parties there when he was about 13. No one checked anyone’s age, he said, and “it was pretty crazy.”
They saw a police report where a woman says she had to climb a gate at one of these parties to escape a man who demanded she have sex with him. Sounds like a great environment for a seventh-grader!
