One should note that while it is true that the last CLISP release was a long time ago and there is not a lot of development going on right now, it's not dead. Bruno Haible just commited last week.
I caution anyone reading this to not take this summary at face value. If you're interested, you should read the linked threads for yourself. I'd say you can leave out that someone followed up on some technical detail three years later, but you be the judge.
FWIW, my takeaway was the exact opposite. How the original async authors were treated was a disgrace. It showed, to me, that there were deep problems with the vim dev community. Forking off neovim was the best thing that could happen. I'm so glad someone had the energy to do so.
That said, I'm super grateful for Brams work on vim. It was my tool of choice for many years.
I admit I know virtually nothing about the aircraft industry, but I always wonder why Airbus doesn't do the initially planned cargo version of the A380. The only reason I can imagine is that there aren't enough customers for the cargo version, but why is this so? Isn't air cargo growing? Would an cargo A380 be too expensive? Some comments suggest the A380 has bad fuel efficiency per passenger mile, but some others suggest this is because airlines put less passenger seats in the plane than possible. Surely this can't be a problem for freight planes? What is it?
