I don't know. Foundation models are very good, and you can get a surprising amount of mileage from them by using them with low level interfaces. But personally I think companies building development tools of the future will use LLMs to build systems with increasing capabilities. I think a lot of engineering challenges remain in scaling LLM's to take over day to day in programming, and the current tools are scratching the surface of what's possible when you combine LLMs with traditional systems engineering.
