This guy is talking about thinking about further down the line for a current project/business, but sometimes my productivity is cramped by these really annoying 'meta' thoughts that aren't even remotely helpful. Like I'll be trying to concentrate, then I'll start analysing how well I'm concentrating, then thinking about things that would affect my brain, and then before you know it I'll be toying with ideas of how consciousness could be manifested in an AI. Totally ridiculous but happens quite a lot.
