How can we exploit the knowledge we live in a deterministic universe?
See yourself as a single cell. If your cell is stimulated in a certain direction it encounters other information then it would if it was stimulated in a different direction. Lets say this cell is stimulated into the direction of education. It would be more likely to be stimulated into a direction of more education for now the cells sees that this holds value.
This knowledge can give us insight in how the universe melds us into certain shapes and we can make use of it. If you have a certain goal in life, making yourself encounter an environment which stimulates you more in the direction of you goal is good a way to achieve that goal. If your cell is aware of its goal and the direction it has to move in to; it can move more rapidly in that direction. For example the cell can pick a movie with a certain subject. Or the cell can pick an documentary over a movie. Every choice you make leads you onto a certain path. Having the awareness of something on a human level we call choice can make you achieve your goals faster.
Maybe this is why awareness/conscious evolved?
