these people are highly trained and are looking to take advantage of technology. Most people do not do these things so, in some instances, the fundamentals of snowboarding are lost in these technologies. In the end, the board just sits there on the snow and does nothing till you strap it on.
If a rider who cannot, lets say carve on a regular all mountain board, will still not be able to carve on a carving specific board. Yes technology can make you faster, floatier or cooler but from what i've seen it cannot make you a better rider.
Take a never ever and put him/her on a regular cambered board and with in a couple of hours, depending on the person, can begin to start to make turns.
Take the same person and put them on say libtech's skate banana and watch them struggle to keep the board the direction they need it to. I've seen this many times.
