How an inept company rules the world
The CPU that runs the world (or at least nearly every mobile phone) is based on the one that was in late 1980 and early 1990s UK school computers (and not really much else except the Apple Newton and the 3DO) until the end of the 1990s (when the actual Acorn machines were going in the skip). It is a little odd that Acorn could be so innovative yet so commercially inept. But then I suppose both them and Sinclair were commercially inept in 1984 over the Sinclair QL and the Acorn Electron. https://www.youtube.com/watch?v=VK5AZrg3ZD8
