At the current rate of increase, by the year 2210 A.D. you will get approximately 4,398 receipts at the supermarket after every purchase with a debit card. This will increase the chit-chat time with the cashier from “awkward” to “frequently verbally abusive.” It will, however, still not change the fact that you will throw all the receipts into the nearest garbage can upon exiting. Or the fact that you don’t write anything down in your checkbook because “it’s all online anyway.” The garbage can will just have to be emptied more often, but that will probably be a robot’s job, so you won’t feel bad. Plus, the back sides of the receipts will still have coupons and some of those will be worthwhile, so you will curse the fact that you can’t afford a robot of your own to sort through the receipt coupons. Instead you will watch as the robot who empties the garbage sifts through your receipts and in turn, gradually becomes the wealthiest robot in the galaxy.
