Oh, yeah - and then this stupid issue - who beats who will decide which style is better, this will win the market. Haha. No one sees the vulnerable point in it : there will be always a "better thing" issuing once money enticed people to fix things in shapes and make patterns for earning money instead of keeping fighting spirit alive. Usually the vicious circle looks like "new discipline comes out, people have attention drawn, market makes room, there is a boom, leaders become haughty and totally ignorant about potential other disciplines developing, fail to notice threat, start to bash on new issued trends, point at which they are vanity-commited on their own position, they are also afraid to change something-market is saturated-wannabees denaturate the thing up to becoming mc-martial systems-politics mixes dirt-people grow demotivated-newcomers seize opportunity and undermine the already old stuff-new thing appears. Common note : effort of generations is wasted, all have to re-invent wheel the n-th time. Good note : capable coaches will shift from one place to another at ease. With some difficulties maybe, but there is scarcely an excellent officer in command who would be so clumsy in modernizing/updating/changing his tools. Actually good ones are good because they are able to foresee trends and adapt even before it is needed.

So finally no reason to be pessimistic. Just the old story : "fortune rota volvitur/descendit minoratus/alter in altum tollitur/nimis exaltatus". (Wheel of fortune turns around, down go the unlucky who diminish; others rise skyhigh, in exaltation). By the way, this is Jerome Le Banner's entrance song - really lovely :)
