My mom tells me that when she was young, the Automat was very popular. An Automat was a slowly revolving vending machine filled with glass covered drawers.
When you saw something you liked — a sandwich or soup or a nice dessert — you would put a coin into the machine and take out the item of your choice. The next time that particular revolving drawer came around, it would contain some other yummy treat for purchase.
Behind the scenes, ladies were working to make all the food and fill whatever drawers were empty. You never actually saw these ladies. To the consumer, it all just seemed like magic.
There is an interesting parallel here with modern A.I. More tomorrow.
