Yep, this is the current sciencism rhetoric.
Right alongside the big bang theories.

But, in this analysis you are missing something big, HUGE.

Sciencism like to divide the world into the known and the unknown.
However, the world is divided into the knowable and the unknowable.
The unknowable is where chaos comes from.

So that idea of knowing exactly how atoms will interact is bunk. We only know how they will interact 99% of the time, while we are watching. We have very little clue of how they interact if we are not watching them. Yes, science gets weird at this point.

There is a quantum science experiment where if the experiment is watched it usually comes up with 1 of 4 outcomes. But, if they take special precautions to not watch it, it has 32 possible outcomes.

Further, being conscious is not being able to think, it is being able to think about your thinking. Thus, being conscious allows you to change your programming. To not react in the same way to the same stimulation.

And the thing that is missing the most in this argument is that the mind is not the same as the brain. Yes, we may be able to make a brain, or a robot that is equal in computing to a human brain, but that doesn't create consciousness. That comes from outside the brain. That comes from the place where dreams come from.

That comes from a place that sciencism will never go.
