All indications are that you can scale LLMs up & down pretty smoothly, I bet there will be lots of workflows in future using AI on pc-or mobile scale hardware which can call out to cloud AI for "deep thinking" or to double check stuff. It seems likely there will be AIs specialised in taxes or medicine, people/systems will consult multiple AIs to smooth out errors and look for consensus etc. In short, I agree with OP that we will probably end up with something that looks more like an ecosystem than a hegemony.
