"Never use AI for skills you want to keep Ferriss draws on his own writing practice to warn about a specific trap: letting AI not only critique your work but then rewrite it for you. He notes that AI models are designed to keep you engaged — 'the model will do, because they want to keep you using the model, is it will give you all the feedback and then it will say, would you like me to incorporate all these changes?' — creating a slippery slope that quietly erodes your synthesis and creative ability. He points to research showing cognitive decline from GPS dependence as a parallel: 'if you lose it, it's a hell of a lot harder to reclaim it.' Use AI for feedback, but always do the rewriting yourself if you want to preserve the underlying skill. Source: Tim Ferriss, The Tim Ferriss Show, AI Q&A Solo Episode"
