I am one of those people who's pretty concerned about AI, but not cause of the singularity thing. (the singularity hypothesis seems kinda silly to me)
I'm mostly concerned about the stuff that billionaires are gonna do with AI to screw us over, and the ways that it'll be used as a political tool, like to spread misinformation and such.
One thing to note, though, is that honey bees are likely a factor in declining native insect populations. Their ability to outcompete native species results in a direct decline in the populations and effectiveness of native pollinators in areas nearby where beekeeping is practiced.
I don't know much about hfcs production, though, so I'll have to look into that.
