There’s another aspect to consider. The problem with editing only with your eyes is that the number of variables (sliders) is too large, and since they are interrelated, it quickly becomes very difficult to find a combination that works, especially for captures that are suboptimal to start with.
At least for me, I want to understand what is going on from a technical standpoint to reduce the amount of tweaking required to get a good image – not because I want my image to be technically correct. For example, if I can nail down the exposure, I may then forget about that slider and concentrate on the remaining ones.
