I'm probably around your age group. Yes we are on the cusp of being totally at the mercy of the digital age. Unless you go off it to the wilds of Canada or some other wilderness you won't be able to exist. Everything will be logged by governments, there will be no cash and what promised to be a wonderful thing (the internet)  will work against us. Like every generation, we point out how "it was better in my day", well in some ways it was but we pay a heavy price for the benefits the modern age brings. Like you, I will get ebay done on my phone browser and on my PC. Incidentally, I think ebay is not the great thing it was. Time for competition I think.
