An Ordinary Man Using AI to Change His Life
Three real experiments. Each one changed something.
Who’s building this
An ordinary Chinese guy.
Two failed businesses.
AI arrived. Trying again.
40s. If I lose this job, I might not find another. My kid enters university soon — into a world nobody can predict.
Goji berries: 6 years, 877 posts, ¥0. Rollup piano: 3 sales, COVID ended it. Now AI. Something feels different. Building in public for 5 years — whatever happens.
