The tool did it because this is what it was designed and trained to do --- at great expense and effort --- but somewahat less than successfully.
You can't have it both ways --- the tool can't be "intelligent" yet too stupid to understand it's own limitations.
If people ask the wrong questions, the "intelligent" response would be, "Sorry, I can't do that".
Maybe the problem here is that this "intelligent" tool is really as dumb as a rock. And it's only a matter of time until lawyers argue this point to a jury in court.
The knives are entering people’s guts. They should not be doing that. The knife companies should be liable for these stabbings.
