If you live in the future: You won't drive, autonomous cars will come to pick you up and drop you off, including round trips. That's why 14 out of 15 car dealerships went bust. You won't use paper, all of your receipts, tax documents, contracts, and mail will be digital and sent to a i-mail address assigned to every US citizen. And you'll view all these documents on your "wall screen". Power cords will found no where…
Funny that you say that, it's pretty much reality in Finland. You can do taxes, apply for benefits etc. online. Not every single thing can be done online just yet, of course.
