How robots are taking over warehouse work

and what are those ex-workers going to do to make a living.

I have watched this disaster build for a number of years now. Before my service, I worked cattle and hay ranches in Washington and Oregon. During harvest they hired 8-10 extra hands. During branding and shipping they hired 4-5 hands. We usually got these from local colleges and schools.
My daughter and her husband run a cattle/farm in South Dakota. With the help of his son, they do 80% of all the work. Most of the time they sit at their computers and enter GPS data. The machines are all run by AI. They plow, seed, and harvest with no "hands on the wheel."
They still have to hire a couple of helpers to process the cattle (branding, cutting, vaccinating, etc.). But mostly it is just them and neighboring ranchers.
The day of the "Cowboy" is definitely over.

MSG Stan Hutchison - Somebody has to fix things when they break. Also known as how I made my living after the Army.

PO1 H Gene Lawrence Automated warehousing has been a thing for decades. While a certain segment of the population tells us we need to go to college, so we qualify to flip burgers and drop fries. Another segment goes to tech school and learns to fix the machines doing the work. Right now in this country, if you are a trained "fixer", you can get well paying work, full time or contract, not temp. Automated is not automatic. There will always be work for people willing to get their hands dirty.

SGT (Join to see) - I am not too sure of that. If AI can be programmed to do tasks, they will eventually be developed to repair what breaks.
I agree for now there will be jobs, as you say, for those that are willing to get their hands dirty. But I am concerned for the future.
