Tax incentives , labor laws,etc..
Yes, stunt growth if that growth is immediately harmful to the public. Provide adverse incentives that increase the cost of replacing humans. Less or no government subsidies, incentives or tax breaks if you replace humans with LLMs. Even without replacing humans, tax LLM usage like cigarettes.
In the short term that is. over time, wind down these artificial costs, so that humans transition to roles that can't be automated by LLMs. Go to school, get training,etc.. in other fields. Instead of having millions of unemployed restless people collapsing your society.
But everyone is on the take, they want their short term lobbying money and stock tips so they can take what's theirs and run before the ship sinks. (if I can be a bit over dramatic :) )
