He was pretty much right about continued computerization, though artificial intelligence continues to be much more limited than the more optimistic predictions of half a century ago. Automation has also not gone as fast as he predicted.
Going into outer space has not happened nearly as much as he had predicted. Some 500 people have gone into space, but only 24 have gone beyond low Earth orbit, and they only went out to the Moon.
I recall him once predicting that programming languages will become more and more like natural language. That has not happened. Attempts to make natural-language-like ones have flopped from being awkwardly verbose. Instead, they continue to resemble the first -level one, Fortran, with its algebra-like appearance. [99-bottles-of-beer.net] has lots of examples across programming languages.
