Much more effort and much more blood would have been spilled if socialism ever "succeeded".

Doing this within one organization, with modern technology, is clearly possible. Attempting this across an economy, in the 70's, where a key premise is "assume you have clean realtime data across all industries," is a fool's errand :) That the ideas sound similar is like arguing Stockfish is based on the original Mechanical Turk. Only true in a superficial sense.

Any larger corporation does this, since at least decades.

It's called "strategische Konzernentwicklung" in german, meaning "strategic development(forecasting) of the corporation" and its markets. A global insurance company I've worked for had something like this https://en.wikipedia.org/wiki/Cave_automatic_virtual_environ... in 2001. I've been involved in planning, installing and operating it. But not the responsible patsy :-) . Which didn't went that smooth, because most users were higher management, and needed holding hands for all the 'complicated stuff', like loading in data, and playing scenarios with those. Also bulky 3D-glasses, and jerky updates, making most people dizzy when standing. All in all several million of Euros for fancy Silicon Graphics hardware and supercustom wall displays and projection, with not so fancy OS and applications. Excel was percieved as more 'productive'.

The demo Formula 1 simulator had its fans, though :-)
