It is also true that it was once really hard, from a technical knowledge and skills point of view, to make video games. There were no engines like Unity or Unreal. Every feature your game needed had to be written from scratch. The artistic tools, particularly for 3d modeling, were crude and had to be adapted by people who understood what the engine was doing.

Now all those things are much easier to do and understand. There are thousands of tutorials on the internet. So making games is becoming more like writing books, putting on plays, making a low budget movie. More people can do it than there is an audience.

The best are still very valuable, in every discipline. But the supply of average people is almost limitless.
