We've spent over 300 years doing the Luddite song and dance. To be clear, I have no problem with Luddites and do not view them negatively, but to imply that this productivity enhancer is magically special in a way no other one was needs some kind of incredibly solid explanation.
edit: as an aside, I do wonder how, if ever, we'll make the transition over to a world where people don't need to work. It seems like every time we think we might be getting closer, the first response is fear.
