at that point humans created the lawn darts that killed kids as well.

Yes, that’s accurate. I’m pretty sure that would be called negligent product design. Where are you saying the lawn darts came from?

There was an earlier observation that lawn darts were regulated because it turned out they were designed in a way that kids could die using them as designed.

I brought it up because in your comment you quoted the following

>> There are no human beings involved

to which you replied

>Humans created and manage the behavior of the automaton.

The no human beings involved is an explanation why the scenario of Alexa telling a child to do something dangerous is not the same as a human on the phone doing it, because there are no humans involved at the time that Alexa says this. This was considered an important distinction to make because if it were like a human being talking on the phone and saying do this dangerous thing the phone would not be considered a dangerous product and only the person would be considered dangerous.

Thus when you say "Humans created and manage the behavior of the automaton." this in context must function as a saying the use of Alexa is equivalent to the use of a phone and therefore Alexa cannot be considered a dangerous product, however the humans involved in Alexa are removed in time and do not take part in the actual dangerous action (in opposition to the example given of a bad actor on a phone call) and thus that a human created and managed the behavior of the automaton is analogous to the fact that humans created the lawn darts.

If the lawn darts are negligent product design then it at least leaves the question open as to whether or not Alexa is as well.
