Customised filters for anyone, but I am talking about filters completely under the control of the user. Maybe running locally. We can wrap ourselves in a bubble but better that than having a bubble designed by others.

I think AI will make spam irrelevant over the next decade by switching from searching and reading to prompting the bot. You don't ever need to interface with the filth, you can have your polite bot present the results however you please. It can be your conversation partner and you get to control its biases as well.

Internet <-> AI agent <-> Human
