It seems to me that the accelerationist argument mainly relies on the fact that international competition is apparent, especially with China who are the main “antagonists” as expressed in the post.
I would like to mention that China is not purely accelerationist, as they have a significant decelerationist backing themselves, that are making their voices heard at the highest level in the Chinese government. So should the US end up slowing down it is not necessarily true that China will for sure continue making progress and overtake us.
We are all human in the end of the day, so automatically assuming China is willing to incur unforgivable damages to the world is unfair to say the least.
This makes a lot of sense. I guess that the most successful bureaucratic companies have optimized for a balance of dominance/status and profit margins. For example a bureaucratic company although not mainly motivated by profits must increase them in order to hire more people, but people cost money, so in order to maximize the dominance hierarchy they must minimize employee cost while maximizing profit.
