2026.02.14 : Himuro Yuri, Joy of Today

Went to see Himuro Yuri's "Joy of Today" exhibition. She's an artist I kept seeing on Instagram, and now that she's gotten famous, she's collaborating with Loewe and even having exhibitions in Korea!

I love that feeling when 2D becomes 3D. Whether it's paint or textile.

One part of the exhibition mentioned that customers also enjoy SNIP SNAP after purchasing, with an example: "Every year, I cut one fish." What an adorable way to ring in the new year! Maybe because I saw it during the Lunar New Year holiday, I thought it was such a fun tradition.

2026.02.16 : Am I the Bottleneck of AI?

I saw a tweet about how you yourself might be the bottleneck of AI. That's exactly what I've been thinking about lately. I used to keep up with new tech pretty well, but now... I feel like I'm the bottleneck. All the agents are staring at me~ everyone's stopped until I make a decision. They're all just waiting for my one answer. It's literally the same struggle as being a real-life PM.

I had fun with Claude Code at the end of last year, but lately I'm worried. Will I be able to keep up with the next wave of tech? Will I survive? Everyone seems to be thinking the same thing.

(Found the tweet)

2026.02.17 : gaemi.world 13F Q4 Update

Updated based on the 13F Q4 filings. I handled the National Pension Service and Cathie Wood -- who reported quickly -- before the Lunar New Year holiday, then updated the rest of the investors.

I also added Korea Investment Corporation to the investor list. The National Pension Service is already conservative, but KIC is even more so -- I thought if you overlay both portfolios, it might reveal what to buy if you want to invest conservatively.

2026.02.18 : Plans of a Gap-mok Day Master

For the Lunar New Year, I asked Claude about my saju (Korean fortune based on birth date/time). I entered my info on a trending page (link below), then passed the results to Claude. I asked about how to spend the next 3 years -- what to watch out for, what to try, that sort of thing.

The advice was pretty much the same as that tweet:

1. Start at least one side project outside of your day job (those who start now will reap the rewards in 2027)
2. Turn your talents and skills into content and put it out into the world
3. Visualize specifically what you want to be in 2032, and take the first step this year

So here's what I did:

1. Set everything up under sejinxjung
   • Currently in the process of switching URLs
2. Tudy Club SEO optimization
   • Continuously fixing indexing errors
   • Added English locale

What's left to do: Make a plan for who I want to be in 2032

Right now I'm feeling pretty anxious. It's like a big wave is coming at me in a wave pool, and I'm scared I won't catch it and just end up swallowing water. I'm trying to keep my pace, but you don't really know how until you're in the thick of it. "Something is coming..." is exactly how I feel right now.

After talking it through with Claude, my takeaway is that it's time to put myself out there, and since I've decided to build my career surviving in startups, I should try everything I can.

There's so much I want to learn and so much I want to do... there's no turning back now!

But 2032 is so far away... Just like how in 2016 I had no idea I'd be starting in the blockchain space in 2022... in 2026, I can't even begin to imagine 2032. Maybe by then we'll actually be getting universal basic income...? Or maybe they'll tax us for having too much data and polluting it. Or maybe Claude will go public and give us token dividends for being early users.

For now, Claude says I should have these things by 2032:

1. An income stream in my own name. At least one source of income beyond my salary.
2. A trail of my work in English. Whether it's content, portfolio, or network -- having the door open to go global.
3. Being able to say "I'm the person who does this." By then, my internal compass should be set. Even if I don't know now, I'll know by then.

So I built a Tudy Club card news generator, but I still need to test it. Building the power of my name -- that's my goal for this year, if I had to pick one.

2026.02.19 : AI, Design This for Me

Apparently there's a tool that lets you prototype wireframes in ASCII. Hmm... will it actually understand what I mean?!

Since Claude Code isn't great at design, I keep noticing design tools. I'm also putting in a lot of effort to strip away that "AI-generated" feel. Is it lucky or unlucky that I majored in design? lol I need to contribute something too.
