Developers say AI coding tools work—and that's precisely what worries them

AI coding tools like Anthropic’s Claude Code and OpenAI’s Codex have advanced to the point where they can build entire applications with human supervision. OpenAI uses Codex to build Codex itself and recently shared technical details about the tool. Professional developers are divided on whether these tools are entirely positive, with some acknowledging their effectiveness while others remain skeptical of the marketing hype surrounding them. Despite differing opinions, there is a consensus that AI coding tools have significantly improved in the past six months, with developers noting a 10x speed improvement for complex tasks.
