As Gerry Mulligan said he does not think about where jazz is going but he doesn't think much of "niche" jazz, and free jazz is chaotic (noise).
As far as where jazz is going, he was too concerned with where he was going to think about that.
Free jazz is "noise" in my opinion, no matter who was blowing it, and that includes JC; Miles said more or less the same thing.
"West Coast" jazz doesn't get any better than the "Gerry Mulligan Quartet".
Enjoy the music.
