This post uses the highly questionable assumption that we will be able to produce a Dyson sphere that can maintain a temperature at the level of the cosmic microwave background before we will be able to use energy efficient reversible computation to perform operations that cost much less than k⋅T energy. And this post also makes the assumption that we will achieve computation at the level of about k⋅T⋅ln(2) per bit deletion before we will be able to achieve reversible computation. And it gets difficult to overcome thermal noise at an energy level well above k⋅T⋅ln(2) regardless of the type of hardware that one uses. At best, this post is an approximation for the computational power of a Dyson sphere that may be off by some orders of magnitude.
This post makes a range of assumptions, and looks at what is possible rather than what is feasible. You are correct that this post is attempting to approximate the computational power of a Dyson sphere and compare this to the approximation of the computational power of all humans alive. After posting this, the author has been made aware that there are multiple ways to break the Landauer Limit. I agree that these calculations may be off by an order of magnitude, but this being true doesn’t break the conclusion that “the limit of computation, and therefore intelligence, is far above all humans combined”.
