> Those 4.5 million survey responses were gathered over a decade
I'd feel more confident about the results of this research if it didn't entirely depend on self-reported data from a survey. At least in this case it was a phone survey and not just an internet questionnaire posted to social media sites. I'd put more faith in a much smaller sample of young people being professionally evaluated for memory problems.
The survey asks the question: "Because of a physical, mental, or emotional condition, do you have serious difficulty concentrating, remembering, or making decisions?"
It doesn't ask what physical/mental/emotional condition they have or even if they were diagnosed with it by a professional (although it does ask if a doctor has told them they have a depressive disorder). Some years included optional questions (which people may or may not have been asked) that gathered a little more information including if they were taking medicine or receiving treatment from a doctor or other health professional for any type of mental health condition or emotional problem, but again, didn't ask what that condition was.
If you told me there has been a surge in young people over the last ~10 years who self-identify as having a mental or emotional problem I wouldn't be at all surprised.

This has got to have a strong selection effect.

I think so, but that hasn't stopped it from being a popular way to gather data, or from often being the only source of data used in a paper. I get that internet surveys are dirt cheap and it's easy to get large number of responses, but you have to take the results with a such a massive boulder of salt that it seems more like a convenient way to churn out papers (or even an easy way to get a desired result) than a way to conduct actual worthwhile research.

I'm not sure it's social media as much as just mobile phones. I used to memorize phone numbers, addresses, directions, short notes, etc.
Memory works like a muscle - use it or lose it.

Quite a while back (I think 10+ years), I began to realize that I was too dependent on Phones for even the basic info. So, I’ve gotten back to writing a lot more and use Notebook + pen. It helps. I still use Phones but I like the idea of being able to know numbers, and details without pulling out the phone for everything.
Using the dialpad instead of the Saved/Favorite Name in the phones is an interesting habit I built up even for most used numbers such as my wife, sister, and even the neighbors. I remember quite a few numbers; even if I cannot say it, I can look at a keypad and the muscle memory kicks in.
This is the same for some key Passwords, I quite often just type them out. Again, I might not remember but my fingers just glides through the keyboard. I remember it being handy at a hospital making some large payment saving my brother’s family from malaria in a Hospital in Bombay.
Btw, it is also fun to no look at Map on the phone for most journey that I already have an idea or traveling for the 2nd time and henceforth.

I recently participated in a research study, and at one point, the researcher told me I was going to be given 3 minutes with a list of 20 words. I was to memorize as many of the words as possible. I would then be asked to perform a specific task, and then repeat back as many of the words as I could.
When I was given these instructions, I realized it's been many years since I had to memorize anything of meaningful length. I spent the first 20 seconds trying to remember as much as I could about how to memorize things, and the rest of the time actually memorizing. It truly is a muscle, and I was very out of practice.

Its the low quality food, my memory improved a lot, after I stopped eating sugar and most refined foods. Theres even some research that Alzheimer starts from bad bacteria in the gut, that loves sugar.

Bacteria (and your body) like sugar because it’s an easy to use fuel source. There’s absolutely nothing wrong with having reasonable amounts of sugar in your diet.

Wouldn't it also have something to do with it being hard to judge quality in the quantity of information today?

Not surprised when you are born in the smartphone era where reels rape your attention and memory.
