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.
Fair point. 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.
But material costs don't matter much in computer pricing.
Exactly… the price of these new materials/CPUs isn’t in the amount of “exotic” elements, which is barely measurable on a per-unit basis, but in the production.
