Type hints are great when using FastAPI. Your inputs are automatically validated, and you get a /docs endpoint that tells people what to expect from your API.

I'd say performance is far from the only reason to consider type hints.

Similarly for Typer, which is literally "the FastAPI of CLIs"[1]. Handy to type your `main` parameters and have CLI argument parsing. For more complicated cases, it's a wrapper around Click.
