A viral thread argues most enterprise AI spend fails because companies automate broken processes instead of redesigning them. explainx.ai on the argument, the 1990 precedent it's drawing on, and what builders should take.

Artificial Analysis shipped Index v4.2 on September 4, 2026 — new held-out evals, GPQA Diamond dropped, 40% private-test weighting. Fable 5.1 leads, Astra wins on cost and tokens.
