same thought I had
I couldn't understand where he was getting these ideas from even.
market pressure as a force field? 😂
The article he linked is quite interesting, though. As most Quanta Magazine articles are, that is.
In a paper posted online in August, Steininger and Sergey Yurkevich(opens a new tab) — a researcher at A&R Tech, an Austrian transportation systems company — describe a shape with 90 vertices and 152 faces that they’ve named the Noperthedron (after “Nopert,” a coinage by Murphy that combines “Rupert” and “nope”). Steininger and Yurkevich proved that no matter how you bore a straight tunnel through a Noperthedron, a second Noperthedron cannot fit through.
They must have had fun coming up with the Noperthedron name~~

Lol yes, even I didn't expect a polyhedron to escape the matrix, I tried to reciprocate the experiment myself without knowing the way they did it, but I lost hope midway.
Its facets, angles, and combinatorial structure are crafted so meticulously that in every possible orientation and cutting plane, no hole large enough for an identical copy can be formed without breaking the convexity or going outside the polyhedron.
Then I realized "Hell no, they were checking a finite (but vast) set of possible “Rupert holes" on computer and I'm being stupid doing it by hand"

Rupee holes ? Does this relate to econophysics and thermodynamics ? Why are you not answering questions and have sus intentions that I’m fake speech hence the counterspeech! Thanks in advance!

You'd be better served reading the article you linked yourself.
That will answer your question.
