That's not how this works. Most airports are looking to expand, they can keep the same staffing levels with a rapid expansion in throughput with these machines. (Assuming the unions allow it).

It's not as though this is a profession which people spend a decade learning to perform. And it's not 2009 any more, there is demand for labor throughout the economy. I think the benefit of getting people out of physically damaging work outweighs the pain of having to find a new job in this case

I don't follow how the existence of these robots is a benefit to the worker. A robot took their job, that does not mean another job was created out of thin air.

I'm not saying this isn't back breaking work, I'm just saying that your logic doesn't make sense.

Many people will be put out of a low-skilled manual job, but many better-paid jobs are created for robot salespeople, robot installers, training specialists, delivery drivers, maintenance technicians etc. Those who adapt to these new jobs will thrive.
