In the future there'll probably be two kinds of people: the ones wielding Magic (aka LLMs)... and the ones trying to hold on to a world before Magic arrived, slowly getting eaten up by the Magic.
And a third group of people, whose jobs interact with the real world, e.g. farmers, plumbers, bakers, hairdressers, taxi drivers, nurses... They can't be replaced by a LLM.
I agree and honestly I already see it starting. For example certain personalities seem to plug their ears and try to ignore it, but then when people around them are already suddenly more productive they are in disbelief. All the other people did was embrace the Magic quickly and start using it.
I bet the distribution would end up like income inequality in Brazil - 0.1% will be magicians, 99.9% will live short brutish lives trying to outcheat each other for survival.
