The fab will accomplish this by harnessing, he says, “some very interesting new physics”.

“We are going to push the limits of physics in compute and do some wild and crazy things,” he says.
Musk says his engineers have developed recursive design and manufacturing processes which will rapidly produce self-improving ICs.
20% of Terafab’s output will be an AI inference processor designated A15 for terrestrial applications.
80% of the output will be a rad-hard processor designated D3 for space-based servers.
Musk is talking about a bigger Starship capable of launching 200 ton payloads into space and putting 10 million tons of computer equipment into space.
