Try 1960 surgery sometime. Or 1960 chemo, or cardio imaging, if you’re really unlucky. Or 1960 airfares or jet engines. Or 1960 machine shop equipment.
The last 30 years? I can exhaustively research a technical subject at home, without getting dressed, thanks to that Russian lady. My Google Drive has a departmental library, suitable for the old Bell Labs, of books on lasers and optics. A CAD (design) and CAM (send machine instructions to a tool) program that was utterly unavailable, with attempts at this in Fortune 50 companies and the DOD, is FREE, with rotatable shaded solid models, FEA tools, and support for hundreds of machines. GPS in a strange area? Cheap expresso makers at home? Adjust your air conditioner from 3000 miles away with your phone? Take studio quality pictures with it? Servomotors and ballscrews on tools now cheaper the gear trains and lead screws they replace? Measure a whole room with a cheap handheld thingy?
OK I’ll shut up.
