Pool is a complicated game but utilizes simple tools.
The cue for example is a simple tool. And for the most part, the industry has always produced cues that were as advanced as the technology and materials have allowed them to be. Sure, there's a certain lag, but then again, this is just pool.
But fear not for the technological future of the cue. Form Follows Function, which we have mastered just fine, which means, there is nothing really left that we need a cue to do, that we cannot get it to do. All there is left to "fix" is aesthetics and personal preference - "the perfect cue" for everyone will never exist.
