Project Prometheus Raised $12B to Train an "Artificial General Engineer." The Training Data Doesn't Exist Yet
Jeff Bezos and Vik Bajaj's startup now has $18.2 billion and roughly 150 employees. What it doesn't have is an internet of manufacturing data, so the corpus will have to be manufactured... much of it on supercomputers.
Microsoft Pulled Its Quantum Timeline to 2029. Physicists Are Still Asking Whether It Has Demonstrated the Qubit
Majorana 2 halves Microsoft's timeline to a scalable machine and reports a 20-second parity lifetime. The preprint measured one observable on one nanowire, unreviewed; critics say that is not yet a demonstrated topological qubit.
AWS quietly retired the fat tree. Fifty-year-old graph theory took its place.
By April 2026, Amazon's random-graph fabric had become the default for most new AWS datacenters. The efficiency claims behind it are still Amazon's own, with no independent benchmark yet.
Britain's Sovereign-Compute Day: A £2bn AMD Bet Meets a £1.1bn State Plan
Britain is funding homegrown silicon for machines that, for now, run on an American vendor's chips. Whether that buys sovereignty or quietly rebrands dependence is the question the spending leaves open.
The Electrician Bottleneck: Skilled Trades Increasingly Gate the AI Supercomputer Buildout
The GPU supply chain has the industry's attention. But the constraint that increasingly decides when an AI factory energizes is no longer the chip. It is power delivery, and the licensed electricians who commission it.
A Court Froze NSF's Supercomputer Handoff. The Operating Model Is the Story.
A federal judge halted NSF's handoff of the NCAR-Wyoming Supercomputing Center. The problem wasn't legality; it was that NSF's process was 'arbitrary and capricious,' and the expertise running the machine can't be quickly replaced.
Co-Packaged Optics Has Two Front Doors. Only One Fixes the Scale-Up Bottleneck.
