I was thinking more about the availability of "molybdenum disulfide and tungsten diselenide" opposed to silicon, they don't sound exactly like Home Depot stuff.

From what I can tell, refined tungsten is actually an order of magnitude cheaper(!) than refined silicon, but molybdenum is over two orders or magnitude more expensive. ~300USD per ton, ~2000USD per ton and ~60000USD per ton respectively.
I assume that if this got up to scale industrially, savings could be made by recycling high purity molybdenum waste, but yes, it's not going to be cheap.

I feel like I'd drop it, and it would crack in half.

CPUs are not made in a home depot.

But material costs don't matter much in computer pricing.

That's very cool, but does anyone else think the title image is AI generated? Neither image nor caption seem to sit right, nor fit together.
Is the 'caption' actually (derived from) a prompt?

This conceptual illustration of a computer based on 2D molecules displays an actual scanning electron microscope image
Sooo ... is it a conceptual illustration, or an actual SEM image?
