Yes, for sure, and there being no repetion of selecting the numbers when calling either so accidentally remembering random numbers doesn’t really happen. (edit: actually now it came to me that when I worked in customer service and would write down customer’s numbers they’d sometimes get stuck in my head! So I’ll just change my point to remembering useless numbers and not useful ones :D ).

But I definitely have no need for the phonebook from before times in my head either!
