This may be overly cynical, but I think it's the lesser of two evils. Historically, we've done an awful job of matching people to jobs. It's depressing to learn what really gets people hired and fired. As an I/O psychologist, I cringe whenever an under qualified applicant gets a job just because they know somebody. So as a field, in general, our goal is to make the process more scientific. As a field I/O is generally pretty positive, but it can definitely be used for evil. The strongest force stopping those folks are probably the equal opportunity laws and regulations.
If you want creepy though, the screening piece is just the beginning. Someday careers could be like your Netflix queue. Based on your past jobs, your performance at those jobs, your ratings of those jobs, your knowledge, skills, aptitudes, and interests, and other factors, your career queue could literally suggest new jobs for you and even line up start dates. That's terrifying for many of us, but for others that peace of mind would be a godsend. If it was mandated it's definitely Brave New World. But if it's voluntary? Then it's not so bad. You don't have to watch the movies Netflix suggests... But how would you ever break out and try something new? I think a poor implementation would be linear, single-career (which we know isn't realistic). A smart implementation which could actually enrich a lot of lives, would encourage career jumps every so many years to help keep people engaged and motivated.
