It’s particularly annoying because those are all AI. AI is the blanket term for the entire category of systems that are man made and exhibit some aspect of intelligence.
So the marketing term isn’t wrong, but referring to everything by it’s most general category is error prone and makes people who know or work with the differences particularly frustrated.
It’s easier to say “I made a little AI that learned how I like my tea”, but then people think of something that writes full sentences and tells me to put dogs in my tea. “I made a little machine learning based optimization engine that learned how I like my tea” conveys it much less well.
So, you’re correct that active emergencies take priority.
That being said, in essentially every place that has 911, both numbers connect to the same place and the only real difference is pick-up order and default response.
It’s the emergency number not simply because it’s only for emergencies but because it’s the number that’s the same everywhere that you need to know in the event of an emergency.
It should be used in any situation where it should be dealt with by someone now, and that someone isn’t you. Finding a serious crime has occurred is an emergency, even if the perpetrator is gone and the situation is stable.
A dead person, particularly a potential murder, generally needs to be handled quickly.
It’s also usually better to err on the side of 911, just in case it is an emergency that really needs the fancy features 911 often gives, like location lookups.
