LPs Should Vet VCs by Asking What They Have Built With AI Coding Tools

A VC's relevance is now tied to their hands-on experience with modern tools. Limited Partners should add a new question to their due diligence: 'What have you built with CloudCode recently?' A lack of practical application is a red flag, indicating the VC may be out of touch with today's builders.
