It will be interesting how this goes moving forward. Agents learn from massive scraping. With the newest tools and frameworks there is nothing but documentation and initial examples to scrape. And now that agent output is flooding everything it can be expected there will be a lot of feedback with automated learning early in development cycles.
Lots of applications have a simple structure of collecting and operating data with fairly well documented business logic tying everything together. Coding outside of that is going to be more tricky.
And if agentic coding is so great then why are there so still so many awful spreadsheets that can't compete with Excel? Something isn't adding up quite as well as some seem to expect.
