Maybe. Pool is about learning the craft. It is the craft. CTE/P1 comes in peripherally as an aid - perhaps. It is not pool.
yes, CTE is an aid, an aiming aid, just like any other conscious method of aiming. And it is a very accurate one. Ghost Ball as Niels' promotes is the least accurate of the aiming method tools that I know of. I get your point and it dovetails with the idea that pool is a romantic gunslinger vibe wherin shooters are born and their deadly accuracy is only sharpened by experience and not getting killed. The idea that all one needs is tons of practice and seasoning against better players on the way up.
The only issue with that is that the vast majority of world class players were made not discovered. They come from the ranks of people who showed interest and aptitude and were supported, encouraged, trained and mentored and seasoned along the way. While on the journey they tried many things and discovered what worked to get them to the level they occupy. Each one of them has a unique toolset combination based on their varied experiences and individual interests.
You can't say for sure that a year from now that a team of brute force semi-ghost ball users who started learning today would be any better or worse on average than a team of CTE-objective aiming users who also started learning today. Without that data the critics who say that aiming systems are a critch are spinning their wheels being obstinate. There are so many variables that broad brush statements saying that CTE stunts overall pool ability are at best likely to be widely inaccurate. And as we only have anecdotal evidence in the form of personal self-reporting of clear improvement the hard data is lacking to say that CTE does in-fact provide significant improvement.
What we do have with those testimonials though are adults who understand pocketing balls and running tables. We have either none or close to no testimonials of any player who describes CTE correctly and demonstrates correct visual acquisition who then says that CTE usage resulted in less shots pocketed than prior to CTE adoption. Conversely we have many who attest to major improvement and who then prove it. CTE users regularly finish high on Playing Ability Tests and Potting Tests when challenged.
I would say that among players that CTE users, given their clear proclivity to be interested in learning that is counter-intutitive, might also understand more about what balls do and how the game should be played than players who just "feel it" using ghost ball to aim. They are likely to be the ones who are absorbing all available information and mining for the gold that they keep. If they are also being mentored by a better player then so much the better for them as they put what they learn into practice.
