It's also that the mindshare of the elite in America was in software and computers until very, very recently where it's branched out to green energy, rockets, and next gen automotives. And we have Musk to thank for at least two out of the three of those.

I also think the natural independent streak running through America (and Canada / Israel / UK / AUS to a lesser extent) draws more of us to software because you don't need to reach consensus to get things done.
