I think it might be because some folks from the older generation have a sense of entitlement...mostly because they often lived through a glorious period that en masse has been beneficial to them...They expected flying cars, etc...So, now, this time they'll get their AI servants...So, its sort of an expectation (for some from this older generation) that the world will keep giving them lots of good (well, good for them!) things in life.
My sincere apologies if my comments are offensive to anyone (of any age group)...but i do agree that I'm seeing way more older people in support of the AI evolution, and many many more younger people fearing it. My age is far closer to the older generation, but lots of times, i'm feeling what i see lots of younger folks feeling: fear.
I think it's much less about generation than about material conditions. It's easier to convince someone that AI is going to be good for their bottom line if they are already retired, or at least have a significant chunk of savings (and therefore investments) and a job higher up the food chain/org chart than a new college grad does. For most working class people, age is a necessary but not sufficient condition to have these things, but there are plenty of older workers who are feeling the fear as well.
