We really don't have any well-documented case of anybody, say, from China visiting Europe or Europe visiting China before the Mongols. But since Chinggis Khan, there's never been a year without contact between east and west. It was permanent. Once he created it, it was permanent.
Okay, my general view is it comes down to something that's pretty simple, which is that if you're doing something in which is very predictable, AI is really nice. When you're doing something that is just not predictable, AI is not very nice to use. If you're using anything that's more cutting edge, AI will not be using it, or AI won't be very good at doing stuff with it.
In fact, even though growth in average infrastructure costs over time is documented, there is very little cross-national correlation between GDP per capita and per-km subway construction costs.
A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com.
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.
About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
