surfing culture has changed a lot...kelly slater's participation led to a big part of the change. i watched him give interviews in a recent andy irons documentary
touched by god and the man is a pure machine - there's nothing laid back or surfer-like about him at all. you respect him for his complete dedication to the craft and willpower to rise to the top of the surfing world no matter what, not for his carefree, anti-corporate, all-too human personality (personified by andy irons and his tragic relapses in/out of drugs while still competing at top surfing competitions)
guaranteed if you go out to your local beach and poll the surfers, 50%+ are well-paid workers in corporate america, otherwise they wouldn't have the means and time to buy all the gear needed and live close enough to the beach to surf as a hobby
the wave machine is perfect for practicing, showing off, and competing for a televised audience, which will bring in more sponsors and of course put more money/attention into the sport. the surf you know is mostly dead [1], which isn't necessarily a bad thing, everything changes
