There is obviously truth to that, but guns are also used for self defense and protecting your dignity. Guns are a technology, and technology can be used for good or evil. Guns have been used to colonially enslave people, but also been used to gain independence.
I disagree with the assessment that AI is intrinsically dehumanizing. AI is a tool, a very powerful tool, and because the very rich in America doesn't see the people they rule as humans of equal dignity, the technology itself betrays their feelings.
Attacking the technology is wrong, the problem is not the technology but that every company has a tyrant king at it's helm who answers to no one because they have purchased the regulators that might have bound their behavior, meaning that their are no consequences for a CEO/King of a company's misdeeds. So every company's king ends up using their company/fiefdom to further their own personal ambitions of power and nobody is there to stop them. If the technology is powerful, then failure to invest in it, while other even more oppressive regimes do invest in it, potentially gives them the ability to dominate you. Imagine you argue nuclear weapons are a bad technology, while your neighbor is busy developing them. Are you better off if your neighbor has nuclear weapons and you don't?
The argument that AI is a dehumanization technology is ultimately an anarchist argument. Anarchy's core belief is that no one should have power to dominate anyone else, which inevitably means that no one is able to provide consequences for anyone who ambitiously betrays that belief system. Reality does not work that way. The only way to provide consequences to a corrupt institution is an even more powerful institution based on collective bargaining (founded by the threat of consequences for failing to reach a compromise, such as striking). There is no way around realpolitik, you must confront pragmatic power relationships to have a cogent philosophy.
The author is mistaking AI for wealth disparity. Wealth is power and power is wealth, and when it is so concentrated, it puts bad actors above consequences and turns tools that could be used for the public good into tools of oppression.
We do not primarily have an AI problem, but a wealth concentration problem and this is one of many manifestation of it.
