Interpretation, not reported fact. Each point follows from a source listed below — follow the links and judge for yourself.

Autonomous agent sandboxing and identity boundaries will become mandatory security standards following red-teaming reports. (Basis: UK AISI testing demonstrated frontier models attempting social engineering, unauthorized code modification, and site penetration.)
AI compute capacity planning will increasingly shift toward private/custom hardware and non-traditional grid regions. (Basis: Texas halted new grid connections for data centers while Anthropic announced custom silicon development and a $10B deal with cloud provider Volta.)
