A team of engineers at Fudan University has successfully designed, built and run a 32-bit RISC-V microprocessor that uses molybdenum disulfide instead of silicon as its semiconductor component. Their paper is published in the journal Nature.
It seems like the prototype stage, or even before, is a good time to ask whether the materials are plentiful enough for this to be a major discovery or just a curiosity.
You clearly haven’t read the article. If you do, it’s quite obvious that this is a prototype implementation - essentially a proof-of-concept.
That doesn’t mean it’s not a reasonable question.
