I'm still on board...
I still get goosebumps when I see old pictures imagining the future. like this one from 1984 showing the Farm Of the Future.
Something about the imaginings of our youth resides in our mental hope chests, perhaps. Or maybe it's just part and parcel of growing up during a time when technology could do no wrong. Regardless, these reminders of what I thought today would be like have the power to make me smile and remain hopeful.
I think the difference is how fascinated we were then with the future. The visions were overwhelmingly optimistic and the idea of science - for many of us at least - as the great benefactor of mankind was pervasive and convincing.
And for the most part, has been proven correct.
