It's wild to think about how short human history is. For example, the iron age started approximately 1200BC, which means that if you are 32 years old you have been alive for 1% of the time humans have used iron. If you are 54 years old then you have lived through 1% of horses being domesticated, the wheel being used for transport, written language and living in towns. 🤯

@gundersen
And if you're 32, something like maybe 20-50% of all iron ever produced was in your lifetime (would be cool to find exact numbers here).

And 99.9+% of all transistors, windmills (by MW), solar panels and many other things.

@notsoloud @gundersen The last two weeks Sweden produced as much steel as it produced iron during the 14th century.
