There’s no such thing as a brainwashing machine. Brainwashing is a very specific process that doesn’t last long outside of the torture or specific scenario that creates it.

What they mean is a conditioning machine.

Confronted with information that could shake their worldviews, people can now search for confirming evidence and mainline conspiracist feeds or decontextualized videos. They can ask AI and their favorite influencers to tell them why they are right. They can build tailored feeds and watch as algorithms deliver what they’re looking for. And they will be overwhelmed with data.

This is, precisely, what morons do. How do you fix stupid?
