I don’t think the rote memorization step per se is important, but the knowledge is. You can pick it up just from doing a lot of math work with those basics. Same thing in chemistry - you will learn most of the periodic table automatically just from doing so many lookups.
But IME, not having the knowledge is a major handicap. I did eventually learn essentially the full multiplication table with speedy recall and it _is_ useful in day-to-day life. I think its basic numeracy on a par with literacy if you ever have to do basics like compare prices for consumer goods, sanity check claimed facts/statistics, etc. I don’t think those skills go away when you have AI anymore than they do when you can “trust” Amazon to do the price math for you.
