If you want to speculate wildly on maybes then it’s also hard to argue that hydrogen is fundamentally one of the most common elements in the entire universe and it’s not particularly controversial to say that a high tech future society would probably want to use that rather than the vastly less abundant heavier elements.

Maybe two decades isn’t spot on, but come on, you’re really grasping at straws.

It’s fundamentally less abundant.

20 years? 50 years? 100 years.

Sooner or later you’re going to run out, and not on geological timescales.

Tell me it ain’t so?

There are reasons to prefer fission, but “we have plenty of uranium” isn’t one of them.
