At the end of the day this is mostly a catamaran racing forum and catamaran racers are a small part of the sailing population, so we don't get the view of the general public here. Depends how you define "the future of sailing", but if it is sales volume then the comment has merit. If it means the future of racing cats then I agree it has no chance. These boats appear to be selling very well.
A guy at my office loves the idea so much he just bought one with the full sailing kit (this is someone who has a cat that he built himself). He is very pleased with it. Anything that gets people sailing is a good thing. This appears to be a very versatile alternative that will probably get more people out sailing than racing catamarans.
