Let me clarify, what I mean is that there is less and less market space for ideas that a one-person army can develop, or at least start developing, by themselves. It's physiological that the industry will eventually completely move away from the "garage type" startups (for lack of a better word) but, are we really already there? Is it time to give up?
Part of the equation is the fact that if anyone can do something, it becomes almost impossible to make a profit out of it. Typical example, virtually every library, even the most obscure ones, of every single programming language has 10+ established courses on Udemy with thousands of votes. Could you make a better, more updated course? Sure you could, but a quick risk–benefit analysis makes it clear that it's not worth the effort.
This goes for a lot of things and it leads to my next point, the local vs global dimension. There is this duality, especially in the broad field of software, where locally you don't need to be literally the best, to have a good career and achieve something. While globally you are always competing against the whole world and you need to be at, and possibly over, the state of the art of whatever you are working on, which in most cases requires to be extremely specialized, to have even a small chance to be recognized, to be somewhat useful for others.
I'm really curious to read how you, fellow Indie Hacker, feel about this and deal with the nihilistic feeling that the world is strangling our space of existence. Except you, captain obvious who are going to write "there is a lot to do!", we all know that, you can spare the effort. 😃
