Eh, I think many of the harms of AI are currently also nebulous. It's not as though the harms are all concrete and massive and the benefits are vague and "in the future"
I agree but I see a lot of very concrete harms too. It's been catastrophic for schools, the sloppification of the web has been largely a disaster so far, it's been a disaster for cybersecurity, it's wreaked havoc on the consumer electronics market, it's driven a lot of financial and existential insecurity for students and early career people across various roles, and while I'm not as militant about data centers as some I think their proliferation has been a net negative environmentally (including increased reliance on coal).
