It’s not exactly clear which emerging technology will bring the next major advance that rock the world but, like an episode of Sesame Street, there’s a good chance that it will be brought to you by the number “5.”

That was the theme of keynote addresses that kicked off Arm TechCon 2018, a gathering of 4,000 embedded systems specialists held in San Jose, Calif., this week. Arm CEO Simon Segars counted through computing history: Wave 1, the era of mainframe computing; Wave 2, personal computing and software; Wave 3, the Internet; and Wave 4, mobile and cloud computing.

That brought Segars to Wave 5, something not so easy to define, at least at this early stage. It will, he indicated, involve computers in everything, but simply seeing it as the Internet of Things is too narrow. The 5th Wave, he said, “is an era of computing that will be data driven. The traditional algorithmic computing will give way to data flowing through machines and decisions made based on what data is telling us.
