Why keep your text legible?
It is necessary to create the content of the site in the most readable way possible, understandable to the user. Google's algorithm is designed to prioritize content that is written most humanly. If your content sounds like it was written by a robot, Google will surely penalize you with a lower ranking.
Of primary importance is the meaning of the written text, which should follow in the most natural way, as well as include topics that people really want to read.
