Obviously, no.

But it's simpler than all the things the article goes in to.

Tech "leaders" get rich(er) if they can convince a bunch of people they have the solutions to their problems. There are various ways to accomplish this and any specific tech and even tech itself is practically incidental.

Each hype wave is just another opportunity to do so. I think tech is generally popular among the people trying to get rich(er) because it's changing pretty fast which provides a regular series of hype waves with regular opportunities to convince people you have the solution they need. (You even get fresh opportunities to convince people they have brand new kinds of problems, which, of course, you have the solution to. Tech is very flexible.)
