Are you familiar with how much child pornography has ballooned from social media? I hadn’t until I listened to this podcast with NYT investigative journalist. Worth considering how serious on of the trade offs are... https://samharris.org/podcasts/213-worst-epidemic/
So, let's walk through this. You have to either have a bunch of people look at child pornography and vet out all that content, or train a neural network on gigabytes worth of child pornography. Either way you want to fight child pornography by collecting and viewing tons and tons of it, as opposed to, I don't know, preventing children from being sex trafficked? Not letting children marry adults?
The biggest porn website on the planet still has trouble solving this problem. Everyone in this thread including bill gates has assumed that this is an easy one to solve.
This is so asinine, especially because bill lumped this problem in with fact checking, which is in a completely different realm of problems.
