s/at the speed of light/no faster than the speed of light/

Information's radiation speed is variable. Lightspeed is its upper limit.

Though yes, some leakage occurs at lightspeed. Fingerprint sound should be somewhat slower in most instances.

I feel like someday we’ll be able to parse the electromagnetic waves that emit from our brain as a result of our basic internal thoughts. That is, it should be theoretically possible to read minds at a distance.

My less polite way of saying this is

"Entropy is a bitch"

That's a very different point.

They are pretty similar. When you look at things like privacy and security in light of human actions and behaviors, then look at our ability to record the entropy from those actions, a whole lot of what we thought was private can be divined by those that can collect enough of this waste.

They're related by the time reversibility of quantum mechanics and the necessary implication that disorder is the broad mixing of initial information.
