We are already there in other sectors. I have worked in Workforce Management and Optimization (WFM/WFO) for the past few years. Scheduling is already common in areas where demand can be easily captured, for example retail banking and contact centers. We use the past data plus other "stuff" to determine the given workload for a position/activity and then schedule employees based on several factors among them are min/max hours, availability, competency, and proficiency. We even have algorithms that determine when you should hire or fire people based on workload.

From my point of view, anything that can measure demand will eventually have automatic scheduling. All those jobs go poof

I think back office is still the current whale in the space. Some of it is harder to determine especially with async work. You are right that thousands of people will continue to lose their jobs here. Back in the day it took my college a long time to process graduation applications. I got a job in that sector that sold software to manage things like students. 6 months of processing buffer down to a button press that takes a few minutes to do everything. So many paper pushes, managers, and other "useless" jobs will go away. Right after that will be those jobs that make sure everything is in order/correct according to business rules and laws. After that will be the huge disruption of lawyers and doctors.

Honestly, I am pessimistic of the future because I see it this way and do not see any political system in my country that is trying to prepare for mass unemployment or people without relevant skills.
