I think producing music for wider audience (music that they can get into) is a bigger challenge.
Also, if you're producing (and listening to) psytrance, you're stuck in a box:
- purists don't let you make a step left or right
- variation between artists is so tiny
- psytrance isn't house or techno, psy only takes from these two, and they evolve much quickly than psy, besides they are genuine, "psy-house" is secondary... and I enjoy house with vocals (not euro vocal house). The same with other psy sub-genres. Basically goa was the only genuine psychedelic electronic music, everything else was already there - you only add some special synths over it and there you've got psy-something.
With all of this you can only get bored with psytrance, being a producer or listener.
UPD: A part from that, we all probably started as teenagers... and people tend to grow up, tastes change too.
