It's something like 3 TUSD, and thus 6% of world GDP (or any
national GDP) which is unprecedented. This is war-scale
spending, involving not only money, but skilled workers,
resources, and energy. We don't have the money, the skills,
the resources (most are peaking) and energy is rapidly
running out.

And of course it had to be actually spent, of which there is
no evidence. Meanwhile, the TW/year net energy debt is racking
up, year after year.
