Here is a great NPR podcast on it. But basically they tried it in California, people liked it, TurboTax didn’t and lobbied against it. They sent you how much you owed and you could verify it, confirm, and send it back super simple.

A lot of the political discussion I’ve read on here has also been pretty well thought out. I feel like people are taking time to explain their perspective more and even if in general it’s been more left leaning there is definitely more nuance. I was surprised by the quality of some of the discussion around the end of affirmative action.
