If someone creates a destroy-the-world button, is only the person who pressed it responsible for the destruction of the world? That's an absurd example, of course, but the point is that you can't just classify something as a "tool" and then leave all outcomes of the existence of that tool as a matter of personal responsibility, that's just cessation of thought. You have to actually think about who is empowered by a tool and in what way. And if a "tool" largely and greatly empowers fakers, grifters, political actors with little respect for truth etc. and the value for most people is largely nil to negative, then I'd say the "tool" is very much part of the problem.
It seems weird to suggest that the supposed legitimacy of the AI hype bubble is caused by anything other than people with a lot of economic and political leverage using that leverage to will something that doesn't really exist into existence. Which isn't that hard given the people they need to convince of its existence are some of the gullible people on Earth, and they do have a product that, while not what they claim it is, does have the veneer of it being that. If a company's shareholders are convinced that AI can replace many of the company's workers (or are convinced that the other shareholders are convinced that it can), then the executives can fire thousands of people and it will just increase the shareholder value. Sure, it will sabotage the long-term health of company, but by that time the locust will have had their payday and moved on to the next grift.
Now of course, this sort of thing has been happening since long before LLMs and the like were a thing, but a key difference is that before, there's been at least some connection between the executives' and shareholders' fortunes and the company actually doing something, given workers at least some leverage to gain and enforce their rights. But now the existence of AI allows them to keep up the pretence that workers have no leverage at all for a good while, so so much for workers' rights. It's not actually AI doing this of course, but the existence of a strategic weapon is still a problem even if the weapon is never deployed and even if it's just a box of firecrackers and pinball machine parts. And that's putting aside all the ways AI is being used as a tactical weapon, undermining education and democracy.
