Of course, if you mean the arbitrary period of time wherein sentient life on this planet may beyond which regress back to a point where communication with other sentients in this Galaxy is impossible...
You may be right.
Since most Obama voters are hard pressed to keep 90% of the fluid stream aimed at the urinal, operating advanced comm gear could be well past their abilities.
Looks like we can add Canadaytimes Commies to their side of the Idiot Equation.
Out at various rest stop and gas station bathrooms along the highways I've traveled, it has never been a comfort to me to observe that several previous visitors to the facility had each somehow managed to pilot their 2-ton vehicular missiles however many hundred miles through the boonies to that location, and walk 25 feet from their car door to the loo, only to entirely miss the urinal at point-blank range.
I figured if I ever ran a gas station I'd electrify the bathroom floor at strategic locations. Really high voltage; fairly low current. Some chowder head gets lazy and next thing he knows he's got a glowing sack of hot plasma and a freaky blue-white arc like the bolt from a Tesla coil jumping up from the floor doing the "Dr. Shrinker" routine in his Fruit Of The Looms.
Of course, to be fair, I'd post a warning sign:
God is happy with my nice, clean bathroom. You'd best keep it that way.
