OpenAI's Codex sees over half prompts from non-engineers, per Greg Brockman tweet, signaling broader AI coding tool adoption and AI industry impact.

According to @scottshics, the development industry is witnessing a paradigm shift where developers are being assessed not on traditional skills but on their 'engineering taste.' Highlighting this trend, an OpenAI Codex-powered project recently ported the entire SimCity (1989) C codebase to TypeScript within just four days, without the developer reading a single line of code. This showcases the growing potential of AI in accelerating coding processes and transforming software development practices.

According to @gdb, OpenAI Codex now runs inside JetBrains IDEs and is available to ChatGPT plan users in IntelliJ, PyCharm, WebStorm, and Rider, powered by GPT-5.2 Codex, enabling planning, writing, testing, reviewing, and shipping code without leaving the editor (source: @gdb on X; @OpenAIDevs on X).
