Engineers at IBM and Google claim they’re closer than ever to making computers that could process data in days that would take millions of years to flow through today’s machines
Colossus was a marvel at a time when “computers” still referred to people—women, usually—rather than machines. And it is practically unrecognizable by today’s computing standards, made up of thousands of vacuum tubes that contained glowing hot filaments. The machine was programmable, but not based on stored memory. Operators used switches and plugs to modify wires when they wanted to run different programs. Colossus was a beast and a capricious one at that.
