Who loves old tech? No I, said the duck.
We had to use those old fiddly electromagnetostrictive delay-line "memories" when we were attempting some of the first practical graphics terminals back in the 1970s. Give me a nice solid-state RAM any day.
Most people who admire those old nostalgic times wouldn't want to actually live there.
Agreed. Old memories (the kind inside your brain) are good, and reminiscing is often a constructive thing to do. Aside from a few video games and other nostalgic things, I am glad we are away from those old, very limited and ultimately very unacceptable by comparison, technologies. They are sometimes EXTREMELY fascinating to see and play with, though.
There are some old technologies that should have been developed further. For example, where'd the propane-fueled refrigerator go? In the 50s they were far more efficient than the electric variety of the day, and they didn't let all of your food rot during a power outage, which are still quite common in some areas of the US, and, of course, the world.
There are some old technologies that could have made things better had they not been killed by the free market, but like Richard, I'm very glad that most of them are gone.
