You are correct in almost everything here, but missing something
that's maybe relevant.
> could have happened in the UK, as they were well ahead of everyone
else in some areas.... large defense budget to further the post-WWII
era of technological development.
It kind of _did_ happen in the UK, but earlier, for the same reasons
of defence funding, but during the WWII era. Characters like Turing
and Cockrell (inventor of the hovercraft), Tommy Flowers (Colossus)
were all "off center wheels" so to speak. They did their work in sheds
using makeshift tools. They got a shot out of necessity. What happened
in Britain between about 1935 and 1955 was an enormous technological
push.
> The reason it didn’t, as I’ve been repeatedly told by people who
live there, is because at that time they had an entrenched culture
that was "anti-anorak"
We still have. Geek never really became cool here. That's an American
thing. But the truth is, after the war we were flat broke. Very few
smart people had the leisure time and capital to risk as in the
US. And then successive governments mismanaged our fledgling computer
industry like ICL and Ferranti.
Today the dominant job prospects for a geek in Britain are working for
Google, Apple, Microsodt, IBM... it's embarrasing, humiliating given
our history, and the disgraceful legacy of successive bad governments.
> SV happened in the US because these so-called anoraks were given a
chance that bore fruit
I think that's the nub of it. But we haven't really learned in the UK.
Our class system and fear of "outsider" innovation is still
entrenched.
