Perviously, the workflow was: - Call local pizza joint, tell them to make a pizza - Pizza joint cooks pizza - Pizza joint tells young kid/local burnout to bring me pizza - Hand young kid/local burnout $$ for pizza, $$ for tip, have pizza. Now: - Tell a publicly traded company to to tell your local pizza joint to make a pizza - Pizza joint cooks pizza - Multinational logistics monopolist-wannabe tells young kid/local burnout to bring me pizza - Take pizza from young kid/local burnout. You may notice a couple insertions that don't seem to make a whole lot of sense, but nevertheless are taking a significant percentage of the, well, not the pie in this case. The pie isn't getting here faster nor does it taste better. Neither the pizza joint nor the young kid/local burnout are making more money. It isn't more convenient. Taking cash out of the transaction legitimately does reduce certain risks. That is an advantage to those who aren't reliant on cash, but note that neither Uber nor Grubhub are required to do that. So the question is, progress for whom?
