Casual observation backed up by no data (yet). Lots of people I work with are using coding agents to write lots of code but so far producing the same amount (or less) of useful output (papers, products, shippable features) Cost of token maxing looks bleak unless you count half working demos.

you might wonder why I am posting edited quotes from reviews lately. Well to quote Popeye:

“<blocked> cannot be a technical contribution as this modification could be used by previous work to achieve the similar results” Dear reviewers, if a paper proposes a new modification in the present that would also improve algorithms from the past, it is indeed a contribution.

A 3D model of a fan disk, reconstructed from signed distance data using (left) classic dual contouring with finite difference estimates of surface normals/gradients, which shows bumps and unevenness near expected sharp curved features, and (right) our improved method, which produces much cleaner and sharper reconstruction of features.

Google Deepmind likes to publish one of these "can VFMs do physics" papers every so often. This year the conclusion is "not quite" last time the conclusion was "its promising" Playing at home ? We're at best stuck and at worst going backwards. video-zero-shot.github.io physics-iq.github.io
