All Those K Languages S Listed, Are Those Evolutions of the Same Language?

The last flight i took before the pandemic was not actually to prague, which was in february 20 20. I can't be upset wisnner about this trip, cause i did not live in new york at the time. But yes, i flew to sort of meet with arthur whitney,. And got to have a bunch of conversations with him and a dinner with him. He said they're deftly not versions. It's not like k three, and was an upgrade from k two. They are complete rerites from scratch. Every single time arthur creates a new language, he delets, like, straight up deleats.
