In Phaedrus, Plato has Socrates tell the story of a dialog between Egyptian gods as a caution against writing—that writing would cause people to lose their ability to remember. On the one hand, Thamus's warning was accurate—cultures that rely on writing generally do not have robust memorized oral traditions—but on the other hand, we only have this story today because Plato wrote it down, and he cannot have been ignorant of the irony.
Every tool has this trade-off, and the existence of skills that will be lost is not evidence that the tool will do more harm than good. I don't think anyone here would argue that Socrates was correct that writing would be the end of memory and wisdom.
> To [Thamus] came Theuth and showed his inventions ... when they came to letters, "This,* said Theuth, "will make the Egyptians wiser and give them better memories; it is a specific both for the memory and for the wit."
> Thamus replied: "O most ingenious Theuth, the parent or inventor of an art is not always the best judge of the utility or inutility of his own inventions to the users of them. And in this instance, you who are the father of letters, from a paternal love of your own children have been led to attribute to them a quality which they cannot have; for this discovery of yours will create forgetfulness in the learners' souls, because they will not use their memories; they will trust to the external written characters and not remember of themselves. The specific which you have discovered is an aid not to memory, but to reminiscence, and you give your disciples not truth, but only the semblance of truth; they will be hearers of many things and will have learned nothing; they will appear to be omniscient and will generally know nothing; they will be tiresome company, having the show of wisdom without the reality."
