Summary
A software developer and worker cooperative leader doing what we simply need to do with AI. And what is that? To bring a vibrant, flourishing society into this world as tangibly and down-to-earth as we can. If you are a Christian like me, you might call it the Kingdom of God, but any word will do—and we can discover that word together.
As a worker cooperative pioneer and bootstrapper practicing "learning by doing", I work to establish IT worker cooperatives firmly rooted in our society—democratic, one-person-one-vote organizations officially recognized under Japan's Worker Cooperative Act implemented in 2022.
