I am 100% sure the Earth will still be orbiting the sun in one hundred years' time. A bit less confident there will be people, playing golf.
The Robert Trent Jones Society? I suppose it will still be going strong, if only to provide future architects contacts to kiss up to in search of "restoration" assignments. Like the Donald Ross Society, his oeuvre provides the most potential for work.
For the same reason, there will probably be a Jack Nicklaus Society, I just wonder whether it will be run by the AI version of Jack?[size=78%] [/size]
