Exactly. Just to amuse myself, I spent a few minutes googling for materials that are "stronger than steel."

spider silk (a classic): https://www.npr.org/2017/01/14/509807212/spider-silk-is-stro...

bone: http://ipfactly.com/human-bone-is-stronger-than-steel/

a graphene sponge: https://www.materialstoday.com/mechanical-properties/news/sp...

carbon nanotubes: https://www.acs.org/content/acs/en/pressroom/presspacs/2010/...

silica nanofibers (because carbon is old news): https://prescouter.com/2013/02/new-material-is-lighter-than-...

fiber-reinforced hydrogel: https://www.global.hokudai.ac.jp/blog/new-tougher-than-metal...

One starts to wonder if steel was ever all that strong. But I'm sure the real lesson is there are a lot of ways to measure strength.
