Your complaints could have been made in the 80s as well. When the personal computer was introduced it removed tons of jobs, Bill Gates became the first 100 billionaire.

But we ended up with lots more jobs than the ones that disappeared. The industry has kept millions of people employed for almost 50 years.

The billionaire founders are usually "worth" far less than the economic activities in the companies they own. Would the same economic activities have happened in a system where billionaires can't appear as a result of the same activity?

I don't see how, and it certainly hasn't happened yet.

Anwyay! Talking to my computer and have it do the things I tell it, like I'm in freggin' Star Trek, feels like a pretty huge upside already! :)
