Predictions are always suspect, but some trends are undeniable. Automation has permeated our culture since the early days of the industrial revolution. The formula is simple - if an industry relies on processes that can be systematized, repeated, and scaled profitably, it will eventually be "disrupted". This is sometimes called "progress", a Darwinian drive to remove inefficiency in pursuit of profit. Do more work. Do it faster. Do it cheaper. Rinse and repeat. Computers have accelerated this, and they consistently get faster and better at it. But one area of everyday life has stubbornly remained immune from automation: the full-service restaurant.
