It makes no sense to spend more to tiptoe through costly incremental steps of infrastructure buildout buying stuff you crave to be rid of when you can hop right to the conclusion. Fuel is bad. You use it and then you need more fuel. That's a vulnerability to the fuel supplier, the logistics, the free market for fuel, changing government meddling. Fix it right once without fuel and be done with it for 30 years. It's not like there won't be another problem to solve the next day.

Or natural gas. No carbon. Carbon fuels amplify the already obscene thermal output by at least 2.5.

Also, none of them is dumb enough to go fission. The time to power is an order of magnitude greater than their expiration date if they don't have it. And their server and power costs are bad enough. They don't need to compound those expenses with the costliest source of energy available.

The transistors aren't actually smaller. It's standard in the field to market the next chip generation as a smaller size when they mean equivalent to the new size. In this case the transistors are stacked vertically so looking down you get layers X areal density of the 2 dimensional surface. We don't do this with flash stacks, which now have up to 321 layers and are mapped to 1000+.

The angstrom scale business is marketing fluff to make the density increase understandable to consumers. But this is one of the developments leveraging the Z dimension that are legitimate progress. The Z dimension gives more than just the same chip folded like origami. The net distance traveled by a signal in a cycle can be reduced, which yields massive improvement in performance without additional cost of power/heat.
