Yes this is basically it. Reticle size is at the limit. Barring some sort of quantum optical revolution, we need chiplets to make more complex chips. Also the amount of heat in a given area is rising. We need to spread it out or find some really innovative ways of dumping the heat. I suspect as time goes on, prices per transistor will become absurdly cheap but you'll need to do things like have redundant hardware running half the time to get rid of the heat.
