The Rolodex was only for less common phone numbers and most people had 10+ phone numbers memorized
You can use the map as a reference but people didn’t use it for drives around town as it is much harder to constantly being referencing a map compared to a gps. Even when people did use Mapquest they would do things like read 2.8 miles make a right on X St and then make a left in 0.2 miles on Y st and look at their odometer and hold the thought in their head that they are looking for X st
And while people did put birthdays on a calendar it meant that they had a paper calendar that they were regularly checking to see what is happening in the future instead of relying on constantly being told that something is happening which while that may sound trivial is a huge distinction in terms of mental processing.
Memory is a very important thing and as time has progressed we have added more and more crutches which help prevent people from forgetting, help the differently abled, and expand our capacity by orders of magnitude but that comes at the expense of a lack of using one’s memory and critical thinking.
What the long term consequences of that are is still up in the air. some preliminary studies have shown “brain rot” but they have had pretty terrible methods and nothing that I would treat as any sort of fact. I however don’t personally see a scenario where it’s positive in anyway and countless studies with the elderly have shown that having a less active mind leads to mental degradation

Do you still have a bunch of friends phone numbers from the last few years memorized? Do you have your local delivery place’s number memorized?
When you go on a road trip you still look at a map, route directions yourself, and develop a loose memory of it?
You can say off the top of your head which friends birthdays are on which days for the next 3 months?
It’s not an opinion that modern technology makes us not have to memorize information that’s just objective fact the debate is about whether relying on technology causes brain damage and that’s where research is still being done.
In the past 20 years really the only “new” thing we have to memorize are passwords which we still had before but they are at least more complicated now but even then many people repeat the same few passwords or use a password manager so they aren’t remembering 10 unique passwords
Using technology to remember things for us is literally one of the fundamental purposes of technology going back to the invention of the written word, manufacturable paper, printing press, computers, and now phones so I genuinely don’t see how you can say that since 1985 you don’t think people rely on technology for memory any more
If you didn’t have a bunch of those common phone numbers memorized then that is definitely a you thing. My whole friend group all knew each others phone numbers and it was actually important that you could memorize those phone numbers in case you had to call from someone elses house or a pay phone.
You even acknowledge that you use a gps for routine travel and think that is the same as developing a mental map?
Again literally the act of looking at a calendar to see future dates is more mentally demanding then relying on getting a reminder sent to you
Did you even read what I wrote? Do you have your entire oral history memorized? No because we have the ability to write it down that’s technology. Do you use password manager to autofill passwords? Do you get text message/app/email reminders of appointments? Do you neglect to memorize things because you can google them? You already said that you use gps for routine travel around town.
All of that involves using memory less, we don’t have enough tech to fully replace memory and probably never will. If you don’t believe me go 24 hours without using technology from the past 40 years for anything not explicitly required for work so no gps, no phone reminders, no google, no password managers then try and do normal things like go run a bunch of errands, cook a meal, pay bills, go shopping in person instead of online
If memory is so important to you than you really need to stop reading and writing. Before literacy was common everyone remembered everything. Knowledge was oral. People had fantastic memories because they had to.
"Report says that in the schools of the Druids they learn by heart a great number of verses, and therefore some persons remain twenty years under training. And they do not think it proper to commit these utterances to writing, although in almost all other matters, and in their public and private accounts, they make use of Greek letters. I believe that they have adopted the practice for two reasons — that they do not wish the rule to become common property, nor those who learn the rule to rely on writing and so neglect the cultivation of the memory; and, in fact, it does usually happen that the assistance of writing tends to relax the diligence of the student and the action of the memory."
Now my mind is filled with knowledge of current ly useful processes instead of facts that aren't immediately useful. I know details of cooking, 3D printing, programming and home repair. Your brain is finite. It's why your memories are deleted when you sleep.

Are you deliberately misunderstanding what I am saying just to argue?
You sure?
I remember my folks having written down the 10 most important numbers on a piece of cardboard on the phone.
And if you were out and about and needed to call someone for help would you have been able to call multiple people from a pay phone?
Tough luck. Hope you remembet your top 3 important numbers.
