Yup. Everything in this thread, up to and including the end. You don't eat around the cockroach.
Let’s talk about abolishing ICE.
Very few people who say “abolish ICE” mean “abandon all immigration enforcement.” Rather, they mean “the structure of immigration enforcement is irretrievably broken and needs to be reorganized, just like we did 23 years ago when we created ICE.”

theres an essentially infinite amount of consensually made adult content online to fit every possible preference, kink and desire
making deepfake porn of others without their consent is about twisted power and control, not being horny

One interesting thing about this is how few articles covering this mention OpenAI’s coming move to integrate ads, which merged with people’s health data, presents a wide range of predatory scenarios.
OpenAI has launched ChatGPT Health. Should we trust it?
The new feature helps users understand test results, get advice on diets and workouts, and prepare for doctors’ appointments.

This. Whats happening w Grok is a supply chain issue: a harmful tool made available for harmful uses.
All the talk of OSAs and yet there does not seem to be a regulatory instrument --or the will -- to actually go after Musk. This speaks more to the failure of our regulators.

We spent long time studying the question "does training data filtering help prevent generative models from generating unwanted content?"
TL;DR: Nope. In some cases it slightly increases difficulty but not enough to prevent even average users from finding ways to create what they want.

Our new paper demonstrates that removing images of children from training datasets of text-to-image models fails to prevent the misuse of these models to generate child sexual abuse material (AI CSAM). A thread 🧵

Why? Print media is cool. Also, 404 Media has watched ICE grow from an already horrifying organization into a deportation force that is better funded than most militaries.
