This guy is not competent to talk about what he's talking about.

Being "forgiving of types" is not a good thing. There's a reason most "type-less" languages have added type hints and the like (Python, Typescript, etc) and it's because the job of a programming language is to make it easier for me to tell the CPU what to do. Not having types is detrimental to that.

while I'm a fan of TypeScript and using type hints in Python from an autocomplete and linting perspective, I am curious...

... has either language leveraged these to better tell the CPU what to do? presumably for perf.

PHP does but the types actually mean something. If your types can be stripped out to make the program run, I have a hard time believing that there is any optimization occurring there.

python ignores type hints
