That's understandable, but think that these people will probably find more fulfilling and productive jobs. As long as the layoffs are gradual, they will have time to retrain and find other jobs. Of course, if their skillsets are really obsolete and many are laid off at once, this can lead to structural unemployment. Eastern European countries went through that after the fall of communism. The transition was not pretty.
But smaller layoffs and career changes are just the cost of technical progress. Have a look at the Industrial revolution [1] and Luddites [2].

Also, here's my first law : "Anything that can be automatized WILL be automatized, whatever the costs."
