I'll go on a limb and say that most of what we have today technology wise was spawned out of military research ( still is today ) and most real scientists will agree. Prior to the post WW2/Viet Nam era that field was largely Americans with a few Jewish/German scientists that came here rather than Russia after WW2. Any other story is an attempt to re-write history to downplay American influence in this era of "one world family crap".

I will back my assumption by regressing to college in the 80's. During my stints to get my Computer Science degrees the demographics were only about 1 in every 20 students ( if that many ) in the Engineering and Computer Science Departments were of direct foreign descent and the instructors were even less. Now it is more like 50% or better. You did not see Americans going to India, Iran, or Europe to get science degrees anywhere near the numbers ( not even close ) as that of foreigners that lined up to come here.

So yes I stand by my assumption that most ( not all ) computer technology advances came from American hands either directly or indirectly. There are articles that have stated just that premise. Take a look at engineering schools in the major universities today and you'll see that trend continues. I am not blaming or finding fault with the foreign students, they did what I would have done in their shoes, I blame us (US) for letting it happen in such an accelerated and invasive fashion.

Not only did we allow our technology to be "borrowed" we financed it through visa programs, school loans/scholarships, and the money we poured into Europe, Asia, and the sub-continent after WW2 via both government spending and the spreading of capitialism and the free markets. How do you think the Arab countries found and started producing oil? It sure wasn't Jed Achmed Clampitt firing his flintlock into the sand. It was our scientists and American companies back in the 50' that started them on their mass producing ride and still today if you go over there you will see American or American trained engineers running those fields, not Arabs. They just get the money as they should in a free market, but we did the work for them. Why do you think Africa is not producing, because we have not spent the money there we did in the Middle East.

It is troubling today to see the lack of American students entering the mathematics/scientific fields in lieu of easier non technical degrees/training.

As I said we are fast becoming a service industry based society and that in the end will prove our undoing. When we took discipline out of schools and began to care more about a student feeling good about themselves to the point there is very little motivation to pursue the hard science degrees our ship sailed.
