Short names on these popular country TLDs are probably not as valuable as they might seem.
I used to own a NN.io domain name where NN was a common financial abbreviation. I thought it might be fairly valuable, but I ended up selling at auction for less than $3k. (That was before the crypto boom. Maybe it could have fetched more if I’d waited several years and sold in 2021. It seems like there was a short moment when even relatively crap .xyz domains sold for five figures.)
Doesn't surprise me. Maybe you've heard of low temperature heat pumps, but not the refrigerants that enabled that technology. You've certainly heard about solar panels but you probably don't know what metallurgical and manufacturing advances made them cheap enough for many people to buy.
Why should someone learn technical jargon when what there interested in is what effects the technology will have on society?
