McDonalds is a great example of this. Minimum wage is headed to $15/hr and they've replaced 80% of the front counter staff with self-order kiosks. Grocery stores can have one person running 4+ self-checkout counters at teh grocery store, and the "gig economy" is just companies skirting minimum wage and benefits via contractors. It's like my childhood paper route for 50 cents an hour all over again...
