And perhaps the people who built and deployed the autocomplete and the connection as well.
Because --if you'll bear with me-- it may of course be much more involved: when (not if) AI models enter life-sustaining systems, such as hospitals, nuclear devices, or food logistics, one of them may get the others to sabotage something resulting in accidents, ranging from mild inconvenience to mass murder.
The person who connected the spicy autocomplete to the defibrillator, or the green house climate control, or the emergency button, is then not the one responsible. Responsibility lies elsewhere, and is nebulous. Think of the Boeing MAX scandal. Did anyone get punished?
That's why it's important to resist it now. Soon, the responsibility of which you speak is gone, and nobody will feel burdened when making decisions with unforeseeable consequences.
I used to hear things like “if cigarettes/alcohol were invented now, they would never allow it”, indicating that consumer protection used to be a thing, as early as 10-20 years ago. Now when AI hit the market it was obvious how bad and dangerous it was, yet governments (even the supposedly good ones in Europe which still [pretend to] do consumer protection) did nothing to protect their citizens from the harms AI was causing.
If we still did (or ever did) consumer protection like that cigarette/alcohol myth above indicates, then the makers of that tool would indeed be responsible for when their products does dangerous things.
Hopefully we never do something silly like making a lead pushing machine that operates at high velocity, then mass produce it, what a terrible precedence that would set.
I think you agree with the OP. In this way, the tool has no ethical problem (there are plenty around how they were trained and such, but that's besides the point), the problems are with how it's used. The ethical problem is how people are behaving and how they are abusing each other, not the tool they are using to exert that abuse.
I suppose it's a little bit of a "guns don't kill people" argument.
The tools have different ranges of uses. A knife can be used to cut things. But while humans are among the things you can cut with it, there is a staggering array of other options which are genuinely useful in everyday life.
A gun can be used to, uh, make small but deep perforations at a distance, by throwing apx. 7 grams of copper-encased lead at high velocity at the target, with somewhat poor precision. Oh, and such an impact does stress/shatter the material around the made perforation quite a lot. So... this thing really can't be used for much anything except for killing animals without getting into contact with them, due to the peculiar way the life is sustained in the animal organisms. This, too, can be useful in everyday life although I personally would advise you, if you find yourself in such a situation, to try and move to somewhere nicer.
