Unless economic systems around the world change significantly very soon, this AI replacement you so cavalierly mention would cause significant portion of human population to reach poverty, causing much unrest and mass deaths.
I don't buy into demonizing the rich, including Altman, Amodei, Musk and co.
I am not concerned that this will be the outcome of the productivity surge.
We will have enough for everyone, and ensuring comfortable living standards for the general population is going to be in the interest of those in power, even if you assume very selfish motivations.
I'd also like to point out that both Anthropic and OpenAI created frameworks to monitor labor market impact and propose responses.
