Ask HN: How much would it cost to build a RISC CPU out of carbon?

RFC: Estimates on program costs to:

Evaluate carbon-based alternatives for fabrication of electronic digital and quantum computers

Evaluate scalable production processes for graphene-based transistors and other carbon-based nanofabrication capabilities

Evaluate supply chain challenges in semiconductor and superconductor manufacturing and design

Invest in developing chip fabrication capabilities that do not require rare earths in order to eliminate critical supply chain risks
