Why spend trillions in decoding human machine when we are ones who run it everyday?

With trillions of dollars being spent on understanding how human body/mind system work, I wonder

1. Aren't we the ones who run this system day in and day out?

2. Shouldn't these dollars be spent on efforts to discover dimensions of our consciousness that are able to connect to the pre-embedded knowledge within each of us?

Lets spend time and effort to break the barriers of limited extent of our 5 senses bound time-space. The question is How?
