How long before the computer decides that they don't need ANY humans?
I don't think it will matter much in the US. Most jobs are becoming marketing-related anyhow. Management is all about bullshit management. I doubt a machine will be very good at such, at least not the first batch of real AI. They may know a jillion facts, but they will be crappy at sales and bullshitting.
I took a few of these e-tests before. I was struck by the amount of MS-centric stuff in them. It asked for all the obscure MS extensions that nobody uses because they suck or lock you in too tight to Gate's ass. Thus, next time I will brush up on all the stupid features that I avoid on purpous.
