I intentionally left out the computers and the internet and all other cool stuff that is happening right now. We already talk about these marvels all the time today. This article was sort of a throwback at the breakthroughs we have made that were so crucial in our development as an intelligent civilisation.
I agree that there are tons of almost magical stuff coming up, especially the decentralised systems like crypto, but yeah, it's fun to stop and think about the past for a bit. Namaste :)
