Since someone brought up boats, here's an analagous bit of history.
Back in the 1950's wasn't it, when the great debate was raging between the "fiberglass is the way of the future and will soon be better than wood" crowd and the "if God wanted boats to be made of plastic he'd have given us plastic trees" crowd.
Half a century later, after the fiberglass people have had phenomenal success building quality, functional, and sometimes not bad looking vessels, history shows they were both right.
Fiberglass and its newer cousins, carbon fiber and kevlar, are fabulous materials and have shown the ability to outperform natural stuff in most situations,
BUT
there is still something about a wood boat, despite the difficulty in getting the materials, the godawful expense, the maintenance, and the weight, that makes a nautical heart go pittapat.
I suppose in 50 years we might be in the same boat (groan) with guitars, huh?
