I am aware most businesses/startups either fail or sell for low millions or have a decent profit but nowhere close to hundreds of millions.

But there are a significant amount of people who have become filthy rich by selling their startups/businesses in short time periods too. And HN seems to have a few of them atleast and many people who know of such people.

So, my question is, what is so special about these people? How are they able to build and run something so complex and sell it for huge amounts? Is it IQ, hard work, connections or something else?

What fields in tech are going to be prevalent, disruptors or gain a foothold in business or consumer markets?

I have seen that people on forums like this one and stackoverflow are usually able to predict the next big things in tech quite well. Like this thread:

So, what CS areas would be good to invest time in learning for the near future?
