There will be no dating. Marriage will have died an unnatural death at the hands of politicians and special interest groupsm, RIP 2013.
There will be no need for dating, because marriage will have gone underground.
But there will be lots of sex. What every kind you like, with whomever you like, as many as you like, as it will be anything goes.
Like the movie "Logan's Run" if anyone is old enough to recall it.
If you were "interested" you went "on the circuit" which was a virtual pick up system (not unlike online dating!) where you scanned the profiles, picked one, and she/he appeared in your house, ready for whatever.
I will watch the whole horrible thing from my nursing home....
