That may be the thinking of some, but for those of us that are actually looking for the taste to improve, checking out some of the parameters that taste depends on to see that they are in (or out) of expected ranges is one of the first steps. Use of tools is what allows man to have espresso, and why, say, dogs didn't develop it. Really, it isn't a bad thing.
Taste depends on a lot of variables. Being able to identify and quantify those variables is a far better starting place than, "Let's do
this and see what happens" ad infinitum, hoping for some eureka moments along the way.
Will some miss the point and take things way too far? You betcha, there is at least one in every crowd. Suggesting that everyone that uses this tool is 'that guy' is off the other end of that same scale, however...
