RE: Changes since you have started and what will change?
I think everyone is right about how technology will continue to provide opportunity for an "easier" hunt; longer range, higher let off, etc. But just because you can do something, that doesn't mean you have to do it.
I started bowhunting in part because I found that shooting deer with a rifle was too easy, there wasn't enough of a challenge for me, nothing against those who do. Just because I'll be able to buy a bow that can shoot an arrow half a mile like a laser, that doesn't mean I will.
I think that there will always be hunters that enjoy the challenge enough to create a niche in the market for the current level (or below) of bows, like the traditional bows today. My .02.
