Where is the frontier
moving next?

About the journal

AI has largely solved the problem of finding information, but there is still a wide gap between knowing something and turning that knowledge into judgment and action.

This journal follows how frontier models, agents, context and memory, AI infrastructure and economics, Physical AI, and Defense AI are evolving and connecting with one another.

Where is the frontier moving next? This journal is my personal record of following that question.
