'The further you get away from your education the less knowledge you have of the new technologies, and technology is always moving forward.'"
I guess that assumes that
1) We, as techworkers, don't learn from our experience.
2) That there is no carry over of concepts from one tech to another.
3) That the technology changes so much that we cannot or do not learn new stuff constantly in the process of working and learning.
4) The technology is the sole thing. There are businesses to be understood and adequately communicated and documented. There is misinterpretation between two engineers who speak the same language, so of course there will be misinterpretation amongst different cultures and standards.
I think there have been plenty of times where I really did things right was after I did them wrong the first time. Other times, one must know a lot to be productive. Yes, we can write 100K lines of code, but if we don't understand how it all interrelates to other components, most of that is not used.
5) That foreigners want to work as slaves for their American masters. I bet within the next decade, we will lose our ability to do any technology here because we will have lost the number of experienced workers to do the design and architecture. I welcome that because it is the only way that the elite will see that tech just doesn't happen overnight. A society that looses its competitive edge will not get it back easily. Look at Germany after WWII. Prior to WW1, Germany was the scientific and intellectual powerhouse in the world. look at the number of Nobel Prizes in physics and chemistry. Since the end of WWII, most intellectuals left to contribute elsewhere. After WWII, there has been a massive brain drain on its economy at a time when Germany needed to rebuild its cities and infrastructure. Another point in fact is that many German rocket scientists went back in the 1970's.
Very soon, you will have major businesses spring up in India and China run by people who repatrioted after learning here. If you ever talk to your Indian counterparts, you will learn that many of them intend to return after their 7 year visa runs out. They know that they are not wanted here, so this will happen from a variety of factors.
