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 [[AIApplicationMarketTrough|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.
