Sorry, but this is just not true.

I'm using agents with a totally idiosyncratic code base of Haskell + Bazel + Flutter. It's a stack that is so quirky and niche that even Google hasn't been able to make it work well despite all their developer talent and years of SWEs pushing for things like Haskell support internally.

With agents I'm easily 100x more productive than I would be otherwise.

I'm just starting on a C++ project, but I've already done at least 2 weeks worth of work in under a day.
