They are doing something extremely valuable. They're basically running planning simulations.

If you're going to spend a trillion dollars a year on something, you'd better spend some time validating your plans for it.

How do you prove they're not?

This is an odd statement, and I can't figure out what you're trying to say.

What are you actually suggesting here?
