Your comments are so apt! I don't know how the get rich quick scheme will go but there will always be people making things for the love of it, and people making things to get one over on someone else. Nature of being human I would guess. I do think it's interesting you pointing out that game devs make games for game devs- I only started doing this early this summer when I promised myself I would make a game by the end of the year, and now I've made a few and really love it. It's like you said- painting for a painter, it's a great form of self expression.
But yeah- the future is definitely weird.
