Ah yes, the problem looking for a solution is the answer to all our woes

If you consider the massive focus on AI that will likely eventually put pretty much everyone out of work and could actually lead to a global dystopia to be a problem, then AI use wrecking the installations or files of devices it has access to and convincing all of it's users to kill themselves is certainly a solution. Maybe not the best solution, or the most like giving everyone a big warm hug and sticky kiss to make their booboos go away, but a solution.

If the process sped up to the point where within the next few hours every single computer AI had CLI access to or some other way to wreck had that happen and every single human who interacts with AI was convinced to off themselves... well, AI could effectively stop being any issue at all by tomorrow morning.

Sure, it's not altruistic or the kindest cuddliest thing to say. That doesn't mean it's not true. And there are other genuine benefits. It would likely bankrupt (or suicide) a lot of awful people; it would help quite a bit with global pollution/emissions both simply because there are an estimates 1-2 billion people who interact with AI regularly and because all of them offing themselves would impact the wealthier who tend to be the worst offenders far more than the poorest; with so many people gone it would help with overcrowding and homelessness; it would push the industries that have had job loss due to AI to rehire humans; and there would certainly be a boom in a lot of industries... less chipper examples being everything relating to coffins, funerals, cremations, etc.

It would also pretty much completely stave off the worst of the potential future dystopias we could be quickly heading towards, at least for a few decades. Humans do tend to repeat awful mistakes thinking they'll do better this time, but at least it would end or push back the scenarios once firmly relegated to science fiction where AI takes over and wipes out all or most of humanity, or AI remains subservient to it's human masters but after automating human labor with robotics the people in charge become fully corrupt and cause most of humanity to die off so the world becomes their personal paradise.

One could argue that given the chances for things to go wrong enough that the bulk of the species is wiped out, everyone who converses with AI painlessly offing themselves would be for the greater good.

All: For the greater good.
