Google has not been scanning gmail mails for ad targeting since 2017. I think after 9 years we can finally let that one go.

Ad display I'll still grant you of course.

I highly doubt that you can prove correctness with types alone.

How would you verify the correctness of this function with types alone:

Integer add(Integer a, Integer b) { return a + b; }

How would types verify for me that the result is correct and not a+b+1?

Formal proofs work for this but to make them work you need more than just types.
