Isnt' that what old-school software did for many years? It used to take jobs, just not from developers. If you implement software that takes accounting from 10 people to 2, 8 just got fired. If you have Support solution helping one support rep answer 100 requests instead of 20, you just optimised support force by the rate of 1 to 5.

I'm in the boat of SaaS myself, but feel a bit dishonesty from Senior devs complaining about technology stealing jobs. When it was them doing the stealing, it was fine. Now that the tables have turned, it's not technology is bad
