I don’t think ARC has particularly advanced the research. The approaches that are successful were developed elsewhere and then applied to ARC. Happy to be shown somewhere this is not the case.

In the case of TTT, I wouldn’t really describe that as a ‘new AGI reasoning approach’. People have been fine tuning deep learning models on specific tasks for a long time.

The fundamental instinct driving the creation of ARC - that ‘deep learning cannot do system 2 thinking’, is under threat of being proven wrong very soon. Attempts to define the approaches that are working as somehow not ‘traditional deep learning’ really seem like shifting the goal posts.
