Seriously, almost any type of 'optimization' on the half of companies/employers right now is bad news for employees and job seekers. We call it optimization because its nice and clean. But the effect of every optimization is to squeeze out every last bit of productivity out of a given work force as possible.
Honestly, I hope this type of thing is never developed and deployed to the degree to which some of the proponents in the article wish it to. They can paint starry eyed pictures of a future where everyone gets to work the job that fits them the best, but all I can see is a future where everyone who has a job is scared shitless of losing it, since it'll blackmark them forever.
