Its about a certain form of reinforced learning, called Temporal Difference Learning:

The calculation is called simple because it follows directly from the definitions above. Simple means more like “follows directly from definition without fancy math tricks”, not " everyone who can read could solve this in 10 minutes".
I think this is also mostly math related, not physics?
I had a good laugh anyway. Good meme
Reinforcement learning is a machine learning (ML) technique (“AI” in layman terms) for optimizing neural networks and other types of non-linear models.
As far as ML math goes, this is fairly tame. It looks complicated, but is spelled out clearly in the paper. A lot of these kind of theoretical papers — things that would get published in Automatica — are going to lean very heavy on math.

Same feeling
I work in documentation. We aren’t allowed to use words like “simple” or “easy” precisely for this reason.
"We can trivially show that…’
Turns out, after a page of algebra, it wasn’t “trivial”.
