This isn't exactly correct. The incompleteness theorem basically
shows that in a sufficiently expressive system, there are statements
in the system that cannot be proven given the language of that system.
We live with this already given the fact that the incompleteness
theorem is closely related to Turing's halting problem. That doesn't
indicate anything about the convergence of programming languages. It
does say that we will need some form of unit testing or restricted
subset simulation system as an adjunct to formal verification in most
cases, until the end of time.
