I would say that formal proofs *ONLY* make sense in the context
of a proof verifier, and this is hardly new, proof of
correctness aided by proof verifiers goes back 30-40 years as
a concept and these tools have steadily improved over time.
A company that deals with such technologies in the Ada context
is Praxis, and a visit to their website is informative.
