Great article!

>"The earth contains a lot of titanium - it’s the ninth most abundant element in the earth’s crust. By mass, there’s more titanium in the earth’s crust than carbon by a factor of nearly 30, and more titanium than copper by a factor of nearly 100."

>"Titanium was nearly as strong as stainless steel, but weighed 40% less."

Consider Steel I-Beams, used in construction:

https://en.wikipedia.org/wiki/I-beam

Observation: If the workability difficulties of Titanium could be solved, at scale -- then not Steel, but Titanium I-Beams -- could be produced, en masse...

If this could be done cheaply enough, then, in the future, Titanium I-Beams -- produced in the U.S.A. -- could retake the worldwide market for construction I-Beams that was historically lost when other countries started producing Steel I-Beams cheaper than the U.S. did...

Anyway, an excellent article!
