Back when I first got a cellphone and slowly started forgetting phone numbers I remember thinking "OK that is scary, it really didn't take long for me to forget something that used to be second nature for me"

@tykling I remember my childhood home phone number and my first mobile number in 2003 but I don’t know my wife of 10 years phone number

Refreshing an existing but faded memory or skill is faster than learning a new one, yes.

For example, I recently played a video game I hadn't played in over a decade, which has very unusual and difficult controls. I was rusty at first, but my old skills came rushing back pretty fast. It took me far longer to learn the game as a kid than to recall it as an adult.

Unfortunately it's also very hard on my elbows now. Adult bodies are so fragile!

Part of the problem is that modern phones don't even *display* phone numbers any more.

Like, I would remember a phone number just by seeing it regularly, even if I don't have to type it in. But I don't even see it regularly.

this post is about the inevitable consequences of not doing the work... convenience culture is toxic at such a low level no one realizes its very profound effects on a body of knowledge few people (even those doing it) give the time of day to: implementing in the real world. Doing real world things--laying brick, building a bookcase, installing a deadbolt, fixing the plumbing-- teaches a body of knowledge largely inaccessible to people who think knowledge is stuff in books

Are you an actual sleuth now?

People were doing division in their heads? Wow. That's hard.

It's hard for computers too, by the way. Division takes much longer than most other instructions, and when a program says to do division, optimizing compilers will substitute a different operation when possible. A division by 2, for example, can be done faster by just shifting the bits, much like division by 10 in decimal is faster.

@patterfloof @tykling That is something I notice, that a quick estimate in your head is often enough, and if it isn't its still enough to check you didn't do anything silly with the calculator...,

You probably also don't know how to make fire with rocks or make rope from tree bark. Or how to saddle a horse.

While you were forgetting phone numbers, you were probably also learning websites, email addresses, and passwords.

Socrates thought that reading would lead to the erosion of memorization.

Did it? Maybe. But things not committed to writing have been lost to the mists of time.

We lose old skills so that we can hone new ones.

@argv_minus_one @tykling I'm not talking about two long multidigit numbers like Ramanujan or anything. Smaller divisions are just reversing times table, slightly longer divisions visualise writing the steps on a piece of paper. Converting to binary first would be a step too far (although thats just division too..)

@argv_minus_one @tykling No, but I have been hunted by a few govt ones (it's not all paranoia)

@tykling I went about 9 months without doing any collaborative software development using Git, and when I returned to it I found myself flailing around hopelessly.

@tykling A bit off the topic of AI: Practise your emergency contacts’ phone number. One day, your life may depend on it.

Short story: My wife got a lorry driver whose lorry sat on top of her to call me from his phone. Worst call ever. But I’m grateful for getting to her before she got taken to the hospital. At the time I didn’t know if she’d survive (thankfully, she did). ️

@tykling Born in 2001 here
First phone I got was a smartphone in ~2014.
The only phone numbers I ever remembered are the family home’s nulber and my own.

At some point I freaked out and started noting a bunch of contacts in a physical notepad. I haven’t updated it in a while now

EDIT: did not read the last sentence. yeah.

One of the few numbers I remember actually is my own mobile number - from all the times I had to enter it or write it down somewhere.

@tykling I remember my own and my wife's mobiles. But not my kids'.

This the hack of using a sharpie to write emergency phone numbers on your body.
