Mypy is not trash at all. It is still the most precise type checker, supports a lot of complicated cases and has plugins that make a lot of things more type safe. I believe Mypy is severely underrated and a lot of people believe that it's not as good as Pyright because of the conformance tests.
The problem is that the conformance tests were mostly written by Eric Traut, so there's a natural bias towards specifying what Pyright does well. There's a lot of things Mypy does really well that should probably be implemented in Pyright.
