About

I'm Sun Zhidong（孙之东）.

I write about personal reputation in the AI era, and I think of myself as a guide / translator for the AI age — making complex AI simple, and helping more people cross the threshold of "not knowing what AI can do for them."

This site is my own open, indexable home base, where I let long-form writing and hands-on project records accumulate. Explainers are an amplifier, not a moat — so alongside the "what is it," I anchor everything to real practice: what I actually built, the potholes I hit, and my own judgment.

You can also find me on GitHub and X (see footer).
