Okay, I apologize I went back and read your first post which said something like "the self doesn't exist is a fun concept to play with" when I was pretty sure you had said just "the self doesnt exist." I'm sitting here trying to find the thread that connects "the self doesn't exist" with your seeming acknowledgement of every aspect of it.
I agree its useful to test "wrong conclusions" for the reasons you state. You end up constructing consistent logic justifying it, and can witness for yourself where the reasoning goes wrong, and can speculate as to why. I think it makes relating to people convinced by faulty logic and conclusions easier to relate to, as well as gives you a hint to where their reasoning is off and you cans start to argue against it
Oh enshittification is coming for Windows. In the future. Like it hasn't happened yet or wasn't the first and worst of these companies for it to come for. But something that hasn't happened yet, not in the past. Interesting.
