Also, being far enough from Europe that a huge amount of talent decided the U.S. was a better bet for getting away from the Nazis. And then taking a large number of former Nazi scientist's post-war as well.
The article mentions but underrates the fact that post-war the British shot themselves in the foot economically.
As far as I'm aware, the article is kind of wrong that there wasn't a successful British computing industry post war, or at least it's not obvious that it's eventual failure has much to do with differences in basic research structure. There was a successful British computing industry at first, and it failed a few decades later.
And yet here we are with Arm cores everywhere you look! :-D
Fair point! That's a great technical success; I didn't realize Arm was British.
If the main failure of British companies is that they don't have U.S. company market caps, it seems more off base to blame this on government science funding policy instead of something else. In almost every part of the economy, U.S. companies are going to be larger.
My understanding is that the British "Arm" is just a patent holder now. I don't think they actually make anything. Companies outside the UK are the ones that actually make the chips licensed from the Arm designs.
