re: In this age of smartphones, do people even remember phone numbers anymore?

There is a clear line of demarcation of numbers that I remember. I remember phone numbers, some of which aren't even current, from around the time I first got a cell phone when I was about 15 and before, and I don't remember the numbers after. What is the point of memorizing numbers now? There is none. It's pointless brain clutter. Mental energy is best spent elsewhere.
