A decade ago I would have agreed with you. But then I discovered the topic of five-symmetries and my absolute favorite non-toxic non-stick pans are coated with that alloy (not long ago deemed impossible) that has the five way symmetry.

So the practical applications are not far behind for these "only 2D" crystals.

Looks like you're referring to https://en.wikipedia.org/wiki/Quasicrystal#Applications, marketed as Cybernox.

But 5 to 13 is a huge jump.

https://www.technologyreview.com/2011/10/12/190784/the-quasi... says "They closed the production line because they had a few problems in the reaction of the coating with salt. If people cook with a lot of salt it will etch the quasicrystalline coating. People didn’t like it, so they did not continue."

I see comments about Cybernox from 2001, so the patents might've expired by now.
