I think they really turned the corner on bows with the parallel limb technology. Then they started working on speed and brace height, which has also improved. Aggressive cams and eliminating shock on the bow when shot has made today's bows quite easy to shoot and shoot well.

Parallel limbs, speed and ease of shooting today's bow can be found in almost any brand made today. I don't know how much farther they can expand bows to improve on what we can buy today...
