Occasionally we suffer a plague of overabundance, like when New Coke came out - there were already more than enough flavors of Coke - one flavor, but then they replaced the old flavor with an updated flavor, and almost everyone now agrees that this was in poor taste.
I was just watching snooker, and the simple elegance of the presentation of the table, equipment, etc. is striking. And the sounds - the sounds are so important, and they sound best knowing that they were made by wood and leather.
Carbon fiber may or may not provide an advantage, but I'd say that in a spectator sport context, wood is a better choice than carbon fiber because it looks and sounds a certain way that most onlookers seem to naturally enjoy more than the looks and sounds of carbon fiber.
As for just playing pool without any audience, I suppose it's a free country, or at least it should be. I think one can still buy New Coke some places, and I've seen a lot of cheap titanium pool cues being sold second-hand, if such things suit one's taste.
