To add another two points to Stefan's argument. Type hinting does not
remove the need to filter user input, but it does allow you to safe-
guard internal functions (library code etc...) against accidental or
internal misuse or improper handling of the data in the front-end
layer. It also makes the code far more readable and understandable not
the mention help doc generation tools that interrogate the code.

Good Morning everyone,
one should not forget that type hinting has some clear advantages the
anti type hinting advocates always try to forget...
* the code gets smaller because not so many typechecks in every
function
* because the code gets smaller it is faster executed (userspace
typecheck is slower than "engine-space")
* without all these type checks the code gets easier to read
* with type hints byte code optimizer can optimize the code far better
-> faster execution
* with type hints static analysing tools that check for
bugs/vulnerabilities can perform far better (intra procedural analysis
gives more information)
