It's helpful to keep in mind that 'AI Twitter' is a bubble. Most people just don't have that many 'important' notes and calendar items.

People saying 'Claude is now managing my life!11' are like gearheads messing with their carburetor or (closer to this analogy) people who live out of Evernote or Roam

All that said I've been thinking for a while that tool use and discrete data storage like documents/lists etc will unlock a lot of potential in AI over just having a chatbot manipulating tokens limited to a particular context window. But personal productivity is just one slice of such use cases
