Everything will (barring certain interactions) evolve to suit a market need, or die off in the process.

It's the wonders of capitalism.

Different people have different needs, and they'll gravitate toward whatever suits their needs. We're hoping enough people want a little nicer and a little more service-oriented experience and are willing to pay a little more to provide that. I am, and I suggest those differences to others when they are deciding on flights as well.
