Shape Your Body These past few days I've been watching videos by @justinsuntron and Luo Zhenyu's "Friends of Time." One of their core plans for 2026 is fitness. They both believe AI will bring a spectacular technological revolution, and we should extend our lifespan as much as possible, improve ourselves, and see how wonderful the future world will be. In Luo Zhenyu's speech, there's a quote from Yuval Noah Harari that's worth pondering: "The most important question in 21st-century economics is probably: What's the use of superfluous people?" If AI and robots can do everything, what can I do? The world is becoming a giant 3D printer. You just need an idea, and AI will handle the realization—what you think, you get. This is a good thing, but thinking further, 90% of the education we received in the past, in retrospect, is meaningless. So, as new parents, we do feel anxious about how to educate the next generation. Luo Zhenyu's speech is very long. If you have similar questions, you should definitely watch it carefully; it's very insightful. On the first day of 2026, the first thing I did was drink 1000ml of water and get a shot of texi, just like the big shots—to shape my body! Then, every day after that, I kept finding ways to enjoy this revolution in the best possible way.
