I remember when I first traveled to Europe over 30+ years ago....
To find our way we used paper maps. Today we have Google/Apple Maps that follow you as you move along.
To get anywhere by mass transit you'd use those maps or find a local transit map and try to figure out where to go.. You hoped you had the right change for the fare. Today, apps like Citymapper not only tell you the way to go, they give you direction to and from your stops and give you arrival times. In most cases, you can pay for your ride with contactless payment.
If you decided to take a taxi, you hoped the driver was honest and didn't take you via some other city. With Ride hailing apps, you can not only order a ride but also know the price ahead of time. Payment is also made through the app.
If you were tired and didnt want to sit in a restaurant after a long day of sighteeing, you'd hit up the local market and try to come up with something. Today, food delivery services are in most cities and let you order from a multitude of restaurants while having it delivered to your door.
Back then, we all had film cameras. Today, for many of us, our phones are our cameras.
I don't remember what I had for entratinment on the long flights over the pond. Today my phone is a book, audio device, movie player and more.
Back then, if I wanted to make hotel reservations or get ailrine tickets, I'd have to see a travel agent. Today, we ask, what's a travel agent?
Anything I forgot?
