The farmer in this piece saw the beginnings of the industrial revolution. That had huge implications but it took a lot of time for those implications to reach the corners of the earth. These days, ideas and technology spread and compound much more rapidly.
Re: Last 20 years, I used to travel in the early noughties before mobile phones were everywhere and none of them had cameras. Wikipedia had barely begun, Google Maps didn't exist, many countries were without ATMs or card connectivity, I even carried TCs once. You you had to pay internet cafes for sporadic internet access. Now I can pay cashless in most places, there's crypto, mobile signals everywhere and global roaming data is a thing. I once got lost in rural India in ~2011, pulled out a laptop with mobile data, a satellite map and a 3D digital elevation model. That's ... superhuman by 1960 standards. And then there's machine translation/video conferencing/libgen/cloud services.
