I have seen multiple posts about this "remembering EVERYTHING", and I think they miss the point. Also they don't quote the context:

> So, coming back to the initial starting point that “you don’t have to remember anything”. The opposite is true. You have to remember EVERYTHING.

I see it like this: it is absolutely wrong to think that you don't have to remember anything. In fact, ideally you would remember everything. The more you remember, the better you can think. Now in practice, it's impossible to remember absolutely everything, so we should strive to remember as much as we can. And of course we need to be clever in how we select what we remember (but that seems obvious).

The point is really that it is common to say "it's useless to remember it because you can ask your calculator or an LLM", and the article strongly disagrees with that.
