The Engelbart perspective on how models can augment our cognitive abilities.
Machines for search/discovery (of patterns I'd add, and novel outliers), role play (?, NPCs?, conversational partner Luhmann like, learning buddy?), structuring, lines of reasoning, summaries. (Of the last, those may actually be needed human work, go from the broader richer to the summarised outline as part of the internalisation process in learning).
Human: access to reality, social context, emotional intelligence, access to reality, longterm memory (machines can help here too obvs), embodied K. And actual real world goals / purposes!
