Yes. I think the emergence of modern computing in the same period didn't help cybernetics at all because everything was (and still is) considered as "computation", although the ever-increasing power of computation, as Ashby noted, allowed the analysis and simulation of "medium complexity" systems along with traditional deterministic and stochastic methods for dealing with the extreme cases.
@Kihbernetics @psybertron Rosen made the case that most systems can't be formalized so that they are computable. We can always design systems that are computable but so far those don't have agent properties. Tough luck.

Disagree with quite a lot you say - but largely because so many large topics are being conflated in short posts 😉
For example - I agree the rise of electro-mechanical computing skewed everything, but unskewed, I have no problem with computation (process manipulation of information) as something much more fundamental.
