What Matters Most The week’s dominant theme is that the AI buildout has run into physical constraints, and the money is now chasing the physics rather than the other way around. Fujifilm is spending $63 million to quintuple production of 100TB magnetic tape because data centers cannot get enough archival storage (Tom’s Hardware); GitHub added 4 million CPU cores and 160 petabytes of storage to absorb a sixfold jump in AI-generated code (Tom’s Hardware); and the grid component nobody thinks about — the transformer — is now a bottleneck serious enough to justify a solid-state redesign (MIT Technology Review). The earnings tell the same story from the other side: Samsung posted a record 107.4 trillion won ($80.5 billion) operating profit on memory demand (Phys.org) while Alphabet shares fell on an AI-heavy cost base (Phys.org). Analysis: the binding constraint on AI in 2027 is not model quality but tape, DRAM, copper, transformers, water, and the capital to pay for all of it.
