What does silicon valley? View the full list of the richest people. Most of these people have no relation to new technologies. It's the financiers. They simply speculate on the financial market. They are parasites.
That is the place where most of the biggest tech companies are operating. Lol seriously? Of course do you know bill gates? the founder of microsoft?(which is an obvious tech? do you know marK? the founder of fb? and larry the founder of google?) both of those are probably part of the 8 men and they are all a founder of a tech company so obviously Tech are taking a huge part of becoming rich
What good is produced by Microsoft? Windows really is not the best operating system. Just due to the fact that bill gates had the advantage due to the fact that he was now cornered the market and will not allow to competitors.
