The Amazon/Helios Idea could work.

Bezos has a very strong track record. Ignition is feasible using converging lasers. Containment is possible with very strong torus shaped magnetic loop. Extraction of usable heat is possible.

Without hot fusion, digital robotics/AI will hit a wall.

It won’t fail, but it will stop growing wildly.

AI is very power greedy.

One data center may need one fusion reactor to keep it fully powered up.

Corporations are using AI to run their companies.

The brains of the executives were never very good.

But AI is good at running complex systems that require milli-second level attention to thousands of detailed data points in real time.

The 3 martini lunch guy in the suit is not as good as the black box on his desk at running day to day business operations.

He’s lucky if he can sit in his chair, and not slip off onto the floor.

The black box on the desk stays put. Works 24/7. Never does impulsive things.
