If 70-90% of people working in AI had been the victim of childhood sexual assault, we would question WTF was going on. Yet ‘sex work’ gets a pass.
2) Yes, childhood sexual abuse (again, also a crime) is associated with both hypo and hyper sexuality. Hypersexual individuals are more likely to engage in sex work.
But I'd hesitate to say that is conclusive without seeing how it is across other professions as well.
I suspect it's more strong correlation than strong causation without more data to the contrary.
