As a senior software engineer, I can tell you that we’ve crossed a threshold in the last six months with Gemini 2.5, GPT-5, and more recently, Sonnet 4.5.
I don’t really code anymore. I prompt and supervise.
I’m still needed, because the AI can drift into strange tangents. But with the right scaffolding and rules in place, Sonnet 4.5 has become an excellent coder. Work that used to take me weeks or months now gets done in hours.
