> It probably is true that on average, only 10% of neurons are firing at a given instant in time. This makes sense. A lot of utilization in nature follows a Pareto distribution, where frequency of use leads to an increase in frequency of use. It's likely that only 10% of roads are in use at any given time, but that doesn't mean that you can eliminate 90% of roads and still have the same capabilities. It's not feasible to utilize 100% of ones brain because there's a fundamental limit to the number of simultaneous activities we can undertake. You might be able to juggle, play an RTS game, figure out the flavor components of a dish, and recite the US Constitution backwards, from memory. What you can't do is all these things simultaneously.
