I agree with you. In a more extreme example, I wish I never offload my address book to my phone, I can hardly remember a single phone number in my head now!
Would you have remembered every phone number if it were in a Rolodex?
It’s a skill you have to exercise no matter where you keep contact information. Same deal with outsourcing directions to GPS-using maps apps: you can still maintain a basic sense of direction and how to navigate a city without an app as long as you make it a point to do so.
