No, the problem is that what is defined as top tier keeps rising, and raises the bar just to be average. You also now have to compete with a huge cohort of people due to the net now.

Going with the videogame focus, if you ever play competitive games you actually see how brutal it can be. In Overwatch for example you have an absolute mountain to climb in ranked because you can't just improve, you have to improve above average to increase your rank. This means a lot of people are getting better at the game over time but are going down in ranking simply because everyone else is getting better faster.

Essentially the internconnectedness of everything is making it hard to find the niches you speak of. There's always someone who loves his job so much and works at it so much that he defines the meta, so to say. This is a problem in computer science, even.
