I believe that the same goes for AI tools for games. Yes, more people will technically be able to produce games. But I think that will shift the focus; it won't be enough with an impressive tech demo in the future, instead you have to connect to the human side of people when you build games.
We now see it as a natural thing that everyone can read and write. We don't want to go back to a time where it was only for a select few elites. If we turn things around and imagine that the technology exists that makes it possible for anyone to build games; then should we keep that from them? In that world, why would we want to gate keep game creation to only people that have time and money to go to a game school or equivalent? You might think "well everyone can learn on their free time", but that's not necessarily true.
I think we will see more human, and more personal experiences that touch us deeper, because they no longer can just be about the technology (since the technology will be commoditized). That's what I'm personally excited about and why I think it makes sense to work on this.
I do agree thought that it can feel overwhelming to look at all this in aggregate. There are already hundreds of thousands of games, why do we need more? But maybe looking at things in aggregate is not the right way to look at it. There have been countless conversations between people throughout history. Does that mean that a conversation is meaningless? I don't think so, and I think (some types of) games will move into this space too; something more personal, something we don't count in aggregate, something that is between maybe smaller groups of people, but more meaningful to those groups of people. At least that's something I'd be excited to see.
