Drink coffee. Read books. Stay happy.

But I’ll still keep using X, of course. Trends show up here the fastest, and a lot of what goes viral on X ends up on Instagram too. I think it’s actually a great tool for marketers and content creators to spot trends early.✏️

Task 10
#HUFSBizCom
I actually started using X last year because I got into ENHYPEN. My friend recommended it to me so I could find more updates and content.
X isn’t that popular in Korea, I just used a private account and mostly scrolled through posts about my fav idol.

[Saeyeon Yoo @SaeyeonYoo]

So I realized it’s really about balance. X can be useful, but you have to be careful, and you shouldn’t click random links without thinking. It also felt like there might be a higher risk of scams compared to other platforms. (just my impression)

I actually prefer studying at my own pace rather than cramming during exam season.
Spent some time at a cafe this weekend just focusing and enjoying the process!! ☕📚

TASK6

I used Claude AI for this, and I strongly agree with these three tips.👩‍💻
Protecting personal info, using strong passwords, and thinking before posting are all so important for staying safe online.

@rhkrtjwls_01 Good point!!
I think people also underestimate how risky links can be.

[Saeyeon Yoo @SaeyeonYoo]

Task 5

AI is easy, but easy doesn’t last.
If you just read, you won’t remember.
Think first, then use AI to check.
Explain it in your own words.
That’s how it actually sticks.

You open ChatGPT. You type the question. A clean, structured answer comes back in three seconds. You read it, it makes sense, you move on. You feel like you learned something.

Forty-five days later, a professor walks in and hands you a test you weren't expecting. You don't remember most of it.

André Barcaui at the Federal University of Rio de Janeiro ran the experiment to find out if the feeling was accurate. 120 undergraduate business students, ages 18 to 24. All told to spend two weeks researching AI concepts, ethics, societal impacts, technical foundations, and prepare a 10-minute presentation.

Sixty used ChatGPT freely. Sixty used textbooks, library databases, articles, and standard web search. Then, 45 days later, with no warning, a retention test.

The ChatGPT group scored 57.5%. The traditional group scored 68.5%. Cohen's d was 0.68, a medium-to-large effect. In most grading systems, that's the difference between passing and failing.

This is called cognitive offloading. When your brain delegates thinking to an external tool, it reduces the mental effort required during encoding. Effort is what makes memories durable. Struggling to find, synthesize, and connect information is not an inefficiency in the learning process. It is the learning process. ChatGPT removes the struggle and takes the encoding with it.

Barcaui calls what the AI group experienced "borrowed competence." The answer was structured, the vocabulary was right, the reasoning felt sound. It just wasn't theirs. And 45 days later, it was gone.

The AI group's forgetting curve was steeper and didn't stabilize the way the traditional group's did. The memories weren't just smaller. They were more fragile from the start.

You didn't learn it. You borrowed it.

Before heading to a cafe to study during exams, I always get my favorite brunch — it honestly makes me way more productive.
I’m addicted to pancakes 🥞
