Consider not holding strong beliefs without empirical evidence. There are both plenty of long term python projects that have held up, and no strong evidence one way or the other on type safety.
I like putting in types just to help my IDE with autocomplete, though. I have also caught a few errors with mypy that could have caused a crash in very unlikely cases. I'm not convinced it's worth rigourously typing a project. It seems like mostly a nerd snipe because I've noticed there is a satisfaction with getting in right despite not making any difference to the user.
