Theuth: "This invention, O king, will make the Egyptians wiser and will improve their memories; for it is an elixir of memory and wisdom that I have discovered."
Thamus replied: "Most ingenious Theuth, one man has the ability to beget arts, but the ability to judge of their usefulness or harmfulness to their users belongs to another; and now you, who are the father of letters, have been led by your affection to ascribe to them a power the opposite of that which they really possess. For this invention will produce forgetfulness in the minds of those who learn to use it, because they will not practice their memory. Their trust in writing, produced by external characters which are no part of themselves, will discourage the use of their own memory within them.
You have discovered an elixir not of memory but of reminding; and you offer your pupils the appearance of wisdom, not true wisdom, for they will read many things without instruction and will therefore seem to know many things, when they are for the most part ignorant and hard to get along with, since they are not wise, but only appear wise."
Which is to say: "All this has happened before, and will happen again."
American and European infrastructure is subject to cyber attacks that that are effectively hostile military acts already. I don't think a vocal stance on Ukraine and an exclusion of Russian developers deserves the rhetoric of McCarthyism or being 'too political' as is these days a fashionable accusation. This is no red scare, this is speaking up for people bombed on a daily basis.
I'm sure it felt very real at the time.
