> effects on poorer countries
For what it's worth, I would predict these effects to be dramatically positive: because LLMs basically immediately counter the effects of being a non-native speaker of your business language, and because the relative change in economic productivity is far greater than the relative change an already-trained-and-fluent worker gets.
All of which is to say, it is reasonable to be concerned about political and economic change, but if your starting position is one of caring more about global solidarity than job loss in the richest countries, I think it's more likely that your concern should be in the direction of "how do I make sure this stays legal and cheaply available everywhere?", rather than the direction of regulation.
