Codex and Claude are already the best programmers in history.
Any task, in any language, they can produce a solution quickly that is right almost all of the time. They don't get tired or complain about having to do brownfield work.
Most business coding is simple and isn't even a challenge for models as they are today.
When OpenAI and Anthropic go public they will be under intense pressure to generate revenue and the first market they will go after (and capture) is business coding; expect their models to get even better at coding than they are now. They will sell "autonomous development" to companies...a continuous development cycle that has little to no human intervention.
I expect most business dev jobs to be on the chopping block within three years, with autonomous development being normal almost everywhere within five.
It's strange to talk to devs who think they will just be coding in five years like they are today.
