Expect robotic fast food in no time!
I have personal knowledge that McDonald’s and other fast food operators have been working on automated food production for some time. McDonald’s already has robotic beverage machines for the drive-thru lane.
And forget about having someone take your order. There will be kiosks with touchscreens for you to place the order yourself, and pay with your debit card. That technology has been available for a long time too.
