Von Neumann pretty much was a god, and even as early as 1945, he was explicitly assuming that neural models were how things in the computing business would eventually shake out.
The rest of us are just a little slow to catch up, is all.
Even if he did predict what would happen, it doesn't mean it's a good thing. von Neumann was a great prodigy but he was also a freak in a way, being able to enjoy the peak of very advanced technical things, which is not necessarily a good thing for the rest of us.
