Open questions
Claims that are unverified, contradicted, or walked back. These are the things to keep an eye on.
- Contradicted Terabase Energy's 'Terafab V2' automated solar array system is part of Musk's Terafab project.
- Contradicted The 'TERAFAB' cryptocurrency memecoin is associated with Elon Musk's Terafab project.
- Unverified Terafab is 'the next step towards becoming a galactic civilization.'
- Unverified Terafab's strategy bypasses ASML EUV lithography backlogs through extreme physical chip scale and custom designs not constrained by mobile/server thermal envelopes.
- Unverified TSMC, Samsung, and Micron cannot scale fast enough to meet Musk's projected chip demand for AI, robotics, and orbital compute.
