Six weeks later Google launched Spark with Gmail, Docs, Chrome and an AI Ultra paywall. This is no longer a tail risk.

Most founders are doing the opposite — hiring to headcount, distributing AI tools evenly, and wondering why nothing got faster.Sun, 10 May 2026 00:00:00 GMThttps://jfsi.io/articles/vibe-coding-wont-kill-programming-languageshttps://jfsi.io/articles/vibe-coding-wont-kill-programming-languagesThe wrong take on AI-generated code is that nobody will need to read it anymore.
