I'm sure it's going in that direction but to what extent we'll reach that point remains to be seen. Note that people lose phones and have to go without them for a while (again, probably more for poor people than others), not to mention even remembering and finding the time to charge them constantly, so it's not as simple as giving everyone a phone. Bear in mind there are lots of other reasons to keep cash; I was just addressing the fee idea.
