> The same line of thought can be used for any (new) tool, say a calculator, a computer or the internet.

Yes, the same line of thought can. But we must also take power into account. The severity of the negative effects of a technology is proportional to its power and a calculator is relatively week.

> Shouldn't we try to find responsible ways of adopting LLMs, that empower the majority?

Not if there is no responsible way to adopt them because they are fundamentally against a happy existence by their very nature. Not all technology empowers, even when used completely fairly. Some technology approaches a pure arms race scenario, especially when the proportion of its effect is mainly economic efficiency without true life improvement, at least for the majority.

Of course, one can point to some benefits of LLMs, but my thesis is that the benefit/cost quantity approaches zero and thus crosses the point of diminishing returns to give us only a net negative in all possible worlds where the basic assumptions of human nature hold.
