Claude writes all of their code. It's honestly a damning indictment of "AI is gonna replace engineers" when all the code the AI guys are giving us is dog.
People aren't going to forums and social media to hype up their own good code to nearly the same degree as otherwise. It's orders of magnitude more negative. There are ways of using AI well and using it poorly. There's no reason to correct your copmetition's unforced errors, or giving away an advantage in using these tools, for so long as there is a moat of effort and esoteric knowledge.
Just because 99% of the things you read are critical and negatively biased doesn't mean the subsequent determination or the consensus among participants in the public conversation have anything to do with reality.
Amodei is on the record about completely automating AI research in 6-12 months. He thinks it's an "exponential" loop & Anthropic is going to be the first to get there. That's not esoteric knowledge, that's the CEO saying so in public at the same time that their consumer facing tool is failing & their automated abuse detection is banning users for legitimate use cases.
I don't consider Anthropic to be one of the teams using AI particularly well. They're building the tools, they're not using the tools in the best, most skillful way possible.
