Well actually, sweeping the floor, Roomba vacuums notwithstanding, may be around as a human job long after a lot of middle class office type jobs have succumbed to a combination of
better speech recognition ( Siri Mk 4), massive data mining and a few codified rules. Once the speech systems are capable of a reasonable conversation...not to pass the original Turing test but no worse than your average CSR at one of the big companies like Rogers or Bell you'll never know that your application has been turned down by a machine.
I would not be surprised, now resumes are sent by email, that some companies don't employ a quite simple program that scans the text throws out ones without the right quals and for that matter, any with dubious spelling and grammar in the body of the resume. Next step...checking previous employment, HR computer to HR computer.
Sometimes I am glad to be out of it all.
