Opening excerpt (first ~120 words) tap to expand
Dwarkesh in the Datacenter by Alex Tabarrok May 17, 2026 at 7:18 am in Current Affairs Data Source Economics Web/Tech Dwarkesh tours one of Jane Street’s datacenters. It’s extraordinary how much compute goes into finance. (I once predicted that the finance AIs would be the first to become conscious, since they have the most compute.) More generally, however, this is a peek inside the remarkable economics, technology and physics of a datacenter. Did you know the electrical signal in a copper wire can travel faster than light in fiber…and that matters! Amazing.
