We experienced another step function in model quality over the summer. Models are now one-shotting medium sized tasks that require significant engineering judgement. We're moving into an era where the production of software will be done entirely by machine, requiring only an abstract description of the need the system is to fulfill in business language. This has been the goal since the 1970s. "Plan mode" isn't necessary when the model can suss out what you need from a few sentences of prompt and make competent engineering decisions to fulfill that need.

Brooks was wrong. We have a silver bullet now.
