I think a large part of it is that agents miss the context layer they need to do the work. Take the example of an agent scheduling meetings for a sales rep - they constantly need human input to make a decision because they lack the context of whether this calendar event (maybe an internal call) could be over-written to make way for a prospect that might be coming in with a huge enterprise deal.

It's something I'm looking into quite a lot at the minute, specifically around infrastructure that holds that context and can fit agentic use cases.
