There won't be any more arguments about pegs, who got there first and so on. The arguments will be about positions on the lake bed. Syndicates could be formed to let out the lake bed by the square foot. Gravel beds would be at a premium, no doubt.
Our boats could be left permanently garaged at the lake, to be activated by remote control, and sent out to fish for us. We can stay in bed at home, fishing in virtual reality. We could have submarine boats, which stay parked on the bed of the lake. Where would it all end? Note that the question can now be asked - the end, then, CAN be visualised....
