For me, a big part of the value of typehints isn’t just the legibility, it’s also helping the interpreter to help me. I can have the interpreter tell me that a string got passed into a function instead of the list of strings that I was expecting, or I can have have my code output a single letter instead of a whole word from the array access call in my code.

I’ll figure out the bug eventually either way, but having the compiler give me the clearer warning earlier in the development process (sometimes even from pure static analysis) is a significantly more pleasurable development experience and a potential time saver

And 50X that, especially the time saved, if I’m integrating with code you didn’t author.
