I am 100% certain automation causes a net loss in human jobs, it's literally it's purpose.

On Retail

When all retail tellers are automated, cleaning and maintaining them is quite literally a 30 minute job for one person to wipe them down. They almost never break, nor need updating. Any change in inventory is done remotely.

On Manufacturing

Manufacturing is on it's knees in the US and damn close to automated everywhere else. Most factories are almost completely autonomous today. There's typically a handful of people (literally less than 10) to oversee a massive factory ensuring things go to plan. Even when these machines break, it takes a handful of technicians to repair them on the very rare occasions they do.

On Creation/Engineering In the creation and engineering field, it's a minimal amount of people who are needed. Apple, the largest company in the world, employs 115,000 people. GE, a declining company and one of the few that uses a lot of humans on the assembly lines, employs 305,000 people. My point being that as automation take jobs, the people who can even afford to get educated, are looking at a much smaller employment field. Even creative fields, such as journalism, is being automated right now. The New York Times literally has algorithms that create their low end articles, and you've likely read an article written by a computer.

Going Forward

So, what does that mean? Well, since so many people in the US are standing firmly in capitalism, and the legitimate concern that the socialism won't work in a large nation such as the US... the future is bleak. We won't be able to afford goods in time, wealth gap will increase, and once there's not a market for luxury goods anymore I really don't know what will happen; but it's not good.
