> Doesn't it? What if those "things" are weapons that you are carrying to battle?
I'm not sure what your point is.
Are you suggesting that some things are better kept close at hand and not on a cart? The invention of the cart does not remove the ability to carry things.
Do you mean to make an appeal to the evils of war? If so, the morality of a use case doesn't have much to do with the efficacy of a technology, though I think you have a point of discussion there. War is hardly always evil, but maybe you could argue that adding efficiency to the ability to wage unjust war is a disadvantage. But, again, you have to get very abstract to make that argument.
You denied a claim that "every new technology benefits some and harms others" by doubting that invention of a cart could cause harm. I'm suggesting a way that it could.
> the morality of a use case doesn't have much to do with the efficacy of a technology
I agree, but I believe it was morality that was under discussion, not efficacy.
> doubting that invention of a cart could cause harm
I think this is where we missed each other. I was trying to address "there is always a corresponding disadvantage", and I think mentally I was interpreting this as "an approximately proportionate downside or externality".
I don't disagree at all that nearly any technological improvement can cause harm.
