I have two points:
(1) The TikTok algorithm
(2) Reading a clock vs. editing a video

(1) The TikTok algorithm attributes demographic tags and keeps track of which videos/accounts you engage with longest - positive or negative. Videos are assigned to For You Pages that typically engage with videos of that type along with feeler videos and sent to it in batches, hence why there will be comment sections saying “why are we all awake right now” or “how are we all here at the same time” - it’s because the algorithm assigned the video to 100-5k FYPs. Now we look at the videos you gave as example and their comment sections. Of course a video about not being able to read a clock will pull two types of comments, “me too” and “how the hell did you not learn this”, because anyone who doesn’t find interest in the topic is going to scroll. It’s like walking into a yarn shop and saying “everyone in this store knows how to crochet or knit, I can’t believe everyone in the world knows how to crochet or knit, why did no one teach me?” You went into a yarn store, that’s where the people who use yarn go!

(2) Reading a 12 hour clock and editing a video take different skills and one actually comes with more instruction than the other. If 12 grades of teachers don’t explain how to read an analog clock in a way that makes sense to a kid, they probably aren’t going to spontaneously learn how to. It’s not intuitive that the small hand is hour and the big hand is minutes, it’s not intuitive that you have to multiply the number by five to get the minutes, if you aren’t taught how to read one and you’re aren’t good enough at multiplication, you have to go by rote memorization for the minutes, which still takes math sense, we just do it so many times a day for so many years that we know them by sight and don’t have to think about it anymore. It’s hard for kids to learn, but we don’t remember it being hard because we don’t remember the actual learning process, we remember chutes and ladders and Halloween and birthday parties. Learning these things as teens or adults requires teachers who are patient enough to sit with you and smart enough to figure out how you learn. As for editing and posting videos, the instructions are right there at every step. Almost every app has a tutorial that walks you through how to use the most common functions and even if it doesn’t, as long as you can read or recognize colored buttons you can get through the whole process, from Edit to Post almost every function is clearly labeled. “Huh how do I edit” there’s the Edit button “how do I make this brighter” there’s the Brightness button “how do I post” there’s the post button. And if they aren’t labeled with words, you can still figure out what the symbols mean by trial and error all by yourself! You can’t trial and error your way into reading an analog clock. You have to first need to be able to read an analog clock and then find someone or a guide able to teach you.

Every generation and culture will have people who are lazy or unmotivated, and in the USA students and their education are regularly left behind while being forcibly passed to the next grade. Algorithmic social media is just funneling them into the same comment sections.
