> The integer types may look similar but they're different in more ways than they're similar. They have different bit sizes, different signedness. The CPU literally has to do different things depending if its `uint8` or `int64`. So why do you want or expect one piece of code that does it all?

Would you say the same thing about registers versus stack-allocated memory? ISAs treat registers and stack-allocated memory very differently, yet virtually nobody wants the "register" keyword in C back and nobody is asking for a similar keyword in Go. (In fact, Go even abstracts over heap memory in the same way.)

"The CPU does it differently" is not a valid argument per se against abstraction.
