Yes, funny, especially this fragment:

"The ray-Jeli-O ® intersection calculations fortunately
require the solution of integral equations and the simulation of
Markov chains [Kajiya, 1986], so they cannot be computed
efficiently. In fact, we have proven that their solution is
linear-time reducible to the traveling salesman problem, where
n is the number of delI-O ® molecules, so we can be sure that
ray tracing Jeli-O ® will be practical only on a supercomputef
[Haeberli, 1872]"

Even my AMD EPYC 7763 has no chances :)
