Random thoughts....
One thing I really love is how we have GPS systems at our fingertips. If I'm in a new city, I don't have to memorize maps and hunt down street names and worry about wandering into a skinky part of town by accident. I just pull out the smart phone, pick a place I want to go, and walk there. I never worry about "getting lost" anymore.
One thing I really hate is what I would call "loss of charm". Like, say, I traveled to some dinky little US southern town, and happened to visit their Class A minor league baseball stadium to take in a game. While at the stadium, I could buy a souvenir cap of the "Podunk Gristmillers" or whatever their team is. The only place in the world where you could buy a "Podunk Gristmillers" baseball cap was to actually go to Podunk and visit the stadium. When you got back home, you could wear the cap and have a "story to tell" about where it came from, and your travels there, etc. etc. It was a way to start a conversation about your travels.
Today, you can order from any of, oh, 280 different websites which sell baseball caps from every city, from every decade, with every variation, and Amazon will deliver it to your front door in 48 hours. No effort, no interesting stories, no "charm".
It doesn't have to be "baseball caps" and "small towns" - purchasing [anything which used to be kind of fun and unique and regional] is effortless and the sentimental, emotional part of it is gone.
