There are now, and always will be people who adopt some form of technology, find it not to their liking, and become evangelists against it. View it like the ex-smoker syndrome. This is human nature, and it isn't going to change. On the positive side, as long as there are water-cooling people who know their stuff and don't mind helping and encouraging new people, there will be new technology, and people to buy it.
The biggest boost we can give ourselves is to allow the market to diversify, and gladly except the fact that there are myriad, valid reasons for water. Not everyone wants to make their own blocks, clock their rigs to high-heaven, convert refrigerators into reservoirs, or pour over reams of esoteric technical data about the thermal properties of water. These are the type of people who have the most potential for driving water, in some form or another, into the mainstream. When/if that happens, we'll find ourselves "soaked" in new, wide-ranging products. I don't see the downside in that.
There will always be room for propeller heads though, no problem there.
