He said "silicon", so obviously he means monocrystalline elemental

much harder and stiffer than steel.

This reference shows elemental silicon only being about 55% as stiff as
steel (112 versus 205 GPa):

Right you are. Monocrystalline silicon is a bit stiffer than that
(though it's variable based on subtleties of composition-- I've found
numbers from 1.30 to 1.88 GPa). I guess it's always seemed stiffer
than steel to me because it _sounds_ so much stiffer, with more than
2/3 the modulus and less than 1/3 the density of steel.
