I think of rayon as being made from tree pulp, and though many fibers are being refined to "micro" fibers, and bamboo is also a tree, fibers of refined rayon compared to bamboo, are only close cousins in "hand."
A century ago, rayon was poo-pooed also, but has evolved from it's category of cheap and shrinking, to definitely serving a purpose. I am sure we will find more and more naturally occurring substances being processed for various uses. At some point the "green" perspective blurs in using so many chemicals to make something natural into a fiber, then textile. I love these new fibers, but I don't think I will will be using them for bobbin or tape laces at this point. Not just because of the time lace takes, but not knowing how stable they are, and for something that hopefully will be passed on and appreciated for many generations to come. As far as milk being developed to assist heart function medically, medicine is so liability conscious, that I doubt the use something that wasn't reliable. (One of my sister's is a VP of a major international company specializing in these things.) Another, is that many heart treatments are projected to last 10-15 years, and then redone, etc. So maybe it won't last forever, but it must be so chemically changed that the body doesn't try to assimilate it, as a body can even absorb a sliver from a piece of wood, etc. in a fairly short period of time, if not removed.
