That's a misconception. Context window of humans is measured in seconds and limited to single-digit amount of entities. Human attention is truly ephemeral, with a ridiculously short span. What you're talking about cannot be emulated by putting everything into the context, you need models with deeper cognitive capabilities, and the longer your context the smarter it needs to be. It can be done by increasing the depth and the size of the model, and by training it better. Test-time scaling does work (longer reasoning, agentic compression, ICL, etc), but hits the wall rather quickly if not assisted by better cognition.
