It's been probably 40 years since I first became aware of the SR-71 myself. I'm definitely not a kid anymore; if I want to feel some sizzle in my SR-71 beans, then I can just get in the car, drive to Dayton, and see one in person.
If that's not nostalgic enough then maybe I can spend some real money on a new-old-stock copy of the first new Lego kit I was given -- set 497 -- and bask in the rose-tinted glory of the past while I put it together on the rug.
But sure: We can make tech cool again. Part of me thinks that tech should be amazing and cool to learn about.
Kids deserve their own new generations of amazing technological spectacles to marvel at, not a resurrection of ghosts from 60 years ago.
Remember how old and archaic it seemed when you were a kid, 40 years ago, and you saw something that was high-tech 60 years before that? We're talking 1926-level tech, here. I sure did love the local history museums that had areas that covered that timeframe, but I recognized them for what they were: Displays of really interesting very old stuff.
We can do better than that for today's kids, but we can only get there by moving forwards -- not backwards.
