Agreed. Past, unfounded worries about proliferation of new mental labour saving inventions is a real thing, but it's wrong to indiscrimately use the analogy every time a concern about such inventions come up. It reminds me of a certain type of developer who blurts out "premature optimization is the root of all evil" every time someone raises a performance concern at design time (I usually ask such people to complete the second part of that Knuth quote or shut up).

Isn't that exactly what Plato's saying? The books cannot understand themselves, and we rely upon them, and in doing so that changes us.
