Despite all these media stories about smug nerds instantaneously fabricating stereolithographic dinosaurs in their 3D printers, most of us still encounter technical failures printing single sheets of paper with writing on them.
Electronics salesmen encourage me to 'invest' in an enormous 3D or 4K television, despite the fact that TV networks never even mastered the art of broadcasting standard definition 2D video properly.
Meanwhile, one of the largest companies in the world wants me to wear their WiFi spectacles on my nose even though I can boast, at least for the present, perfect vision. Offer me Google Pince-nez and matching Microsoft smoking jacket for use at home instead and I might be interested.
But then, like all the tech gurus and other professional futurists with their wild-eyed, breathless prognostications for 2014, I'm already getting ahead of myself.
Happy New Year: keep it simple, stupid.
