Looking at where we are now you might say, "Well it's not that unbelievable..... It's just logical! We were bound to get there someday!"
If my grandfather were alive today and you showed him those two devices pictured above.... he would first of all, smack you.... then tell you to go get your head checked by a doctor. And then he would smash your iPhone and say something along the lines of, "How great can it be? It breaks easy enough!"
But take it back another generation to my great grandfather, show him how you can pull a Christmas tree out of a box, plug it straight into the wall (pre-light tree!), and then turn it on and off with your iPhone. And he would probably accuse you being a magician or the devil..... depends on what his mood would be.
Looking at why: The cell phone didn't exist in his day & age, Christmas trees had to be cut down by hand, they sure didn't come out of the woods pre-light, and somehow you just managed to turn the Christmas tree on and off without touching it!
NONE of those things would seem logical to him. So who's idea was all of this!? And how do I get their job?
