It's interesting how slow the uptake has been. 10GbE is from 2002, 24 years old. It's much worse than IPv6, at least we're up to 50% uptake there.

100 GbE is 15 years old too depending on which standard you think of. (The most common physical layer, SR4, is 11 yrs old)

Gigabit ethernet came much faster after 100 M.
