It's a fair point. It is not a blind spot -- I did think about it, but I don't think I have ever owned an Asian-designed computer or used Asian-designed software. Ditto African or Australian, FWIW.
I once owned a 2nd-hand Sony Ericsson P910, an early smartphone with the UIQ GUI -- but this was a Symbian device with a Swedish-designed UI. I'm honestly not sure how much input Sony had. And I have a Playstation 2. My tablet is Chinese, by a Chinese company (Chuwi), but it runs an American OS: Android. These are about as close as I can claim, sadly, so I am really not fit to comment or judge.
Whereas most of the world's electronics are partly or totally manufactured in Asia, it's mostly by or for American- or European-owned companies.
I am aware of many fascinating Japanese computers and similar devices, from the FM Towns to the Pomera e-ink portable word-processors, to the MSX2 and MSX2 Turbo-R computers, which interest me greatly and I'd like to have -- but I don't.
The Julia programming language (AIUI, an Indian project) looks fascinating, but I am a poor programmer and old enough to find learning new languages extremely hard -- not something I would do as a leisure activity. So I have never tried it myself.
There is no lack of creativity there, certainly. There is a huge amount. It is just that little of it seems to directly influence the world market elsewhere.
Why that is the case is a fascinating question that I am ill-equipped to address.
