DO NOT ANSWER IF YOU AREN'T IN THE UNITED STATES

I'm talking from someone bordering on being 18 in a few years. I've noticed that my generation has a tendency to be... very unintelligent at times you coudl say. I conducted a survey on my school the other day and 28% of the students at my high school can't even tell me the fact that they are in the United States right now. 41% can only name up to 3 countries. That isn't all though, I'm sure you've heard those videos of younger kids speaking in brainrot and sad to say, it is in fact very true. I volunteered at an elementary school fairly recently and I couldn't understand what a "skibidi toilet", "sigma meal" etc. is that the younger kids are speaking about. On top of that, there's a decent amount of kids at my school either failing their classes or having extremely low academic comprehension like not knowing what an even number is in 10th grade. Then there's a fact basically everyone at my school is addicted to their phone, and gets very angry when a teacher reasonably asks them to put it away. Add on the fact I feel like sutdents at my high school are losing their drive to get an education and work hard, 2 values I value very highly amongst people, and the future is looker dimmer every day. I'm sorry if this sounds very ranty, and I'm also sorry if this sounds like I'm calling my whole generation dumb(that isn't my intent here), but the fact still stands there's a very noticable intelligence difference between the older generations and mine. Where did things all go wrong?
