For me it's the "memory" augmentation that is likely most valuable. Sure I want to learn things, but I feel like I need to make mental space for new things. Offloading that memory to writing things down, or having an observer annotating it for me, would be a great help by an agent. Also, the most important thing I learned in business school was that there are frameworks for EVERYTHING. It's extremely rare that a problem we individually face has not already been analyzed to death, drawn out, addresses, and solved and written down -- so we can all learn. Agents are basically framework engines, and can remind us what others have done already, so we can grow and expand on it.
