As exelius mentions, a large part of the demand involves companies that are a little schitzoid and dysfunctional, who have decided it's easier to throw money at the problem and use technology to paper over the cracks.
There's going to be big dysfunctional corporations for decades to come. There's no guarantees in life but investing a little time in a technology like that is probably going to pay for itself and much, much more. I wouldn't do it but I can see why someone would.
