No? Calling them advanced is one thing (because it was advanced up to their elimination/dispersion), saying it rivals modern materials science is ridiculous, and is a statement that appeals to the people that buy crystals for their "healing energy". The peoples born of the America's do not benefit from Burning Man-type bullshit.

Romans made self-healing cement without any knowledge of chemistry and materials science. Surgeons performed tumor removals without knowing why they formed. Etc.
