No, it's definitely a separate observation. The Entscheidungsproblem describes a problem space that we cannot build a machine to solve.
What Kawai is saying is a more physical thing - even for problems we can build a machine to solve, the machine will eventually stop working under normal use, and it's unlikely even to produce consistently correct results.
