曲凯 / Qu Kai

Qu Kai is the founder of 42章经 and the host voice in AI 发展了 4 年，把应用发展没了？｜AI 年中复盘. The source presents him as an observer of the AI venture cycle who has done repeated annual AI recaps and uses founder/investor conversations to interpret how market attention moves between models and applications.

In this episode his wiki role is the source’s synthesis voice. He argues that AI application pessimism is real but not final, that founders should follow model waves without performing for capital taste, and that AI product value ultimately returns to users, scenarios, payment, and cash flow.
