When he died, I missed him.

I really think that his ideas are good if it was in motion, but really really hard to set them in motion.

I think the main flaw would be something like this:

Imagining that a big computer magically could tell how many resources are on Earth, everything is monitored, and there's a system where you could ask for "10kgs of iron to a project in my garage" or "for my students", the system calculates and say "yeah, that is not destructive, I can provide you with that". Good.

Then, a group wants to build the LHC, evolves science, great stuff, the computer says "yeah... about that, that is A LOT of resources, I don't think I can provide you that." And if we "override" to say "this specific project should deserve this many resources", anyone with some kind of power could allow other people build this.

Small resources, small projects is easy to run on this society. Big projects would have a big problem.
