I suppose there is something in our culture. A lot of inventions and science has come out of the UK.
There's also an (I assume) cultural phenomenon of tinkering in the garden shed.
I suppose there's the Protestant work ethic, the ethic of self improvement, a general acceptance and perhaps celebration of odd balls and tinkerers.
It the field of computing, it probably helps that we speak the same language (ISH) as the us, where a lot of this tech came from, but didn't have the money to just buy solutions.
But I don't really have any experience of other cultures in this context to say whether these things are unique.
