I've been a proponent for a long time, so I certainly fit this at least partially. However, the combination of Claude Code and the Claude 4 models has pushed the response to my demos of AI coding at my org from "hey, that's kind of cool" to "Wow, can you get me an API key please?"
It's been a very noticeable uptick in power, and although there have been some nice increases with past model releases, this has been both the largest and the one that has unlocked the most real value since I've been following the tech.
