And "China" didn't do anything, a Chinese company did. Some very weird headlines lately.
That kind of hot swap exists for servers, but for general consumer stuff there is USB. It can move gigabytes per second.
Since it started as his personal project he was the leader from the beginning. And since he turned out to be a capable leader and never got bored and left there was never any reason to take away that authority as it skyrocketed in popularity.
Basically, he's King because he founded the Kingdom.
The trouble a successor King would have is they could never have that kind of legitimacy, so some kind of more "Democratic" structure (self-appointed electors) is the most likely follow up.
The co-producers of Concorde would have nothing to gain from close up photos of their only rival in the air?
The Tu-144 had a few interesting ideas, but of course they didn't know it was mostly inferior without getting the intel.
If the successor is another benevolent dictator then we're looking at a monarchy, and it's a dynastic succession.
If he names a successor, especially beforehand, then the community gets a veto, and if the candidate passes they can probably take the reigns when Linus leaves.
If he doesn't name a successor then you get a bunch of claimants, each arguing for their legitimacy to the throne.
If one wins the argument they can still succeed him, but there's a serious risk of fragmentation (long term forks) or simple infighting.
If you want a benevolent dictator (King) you need to give them maximum legitimacy, and that means naming the successor early.
Nope, the Kingdom is the project with all the relationships and developers attached.
As I said, unless someone is specifically endorsed by Linus (and maybe not even then) I'm not sure anyone has the legitimacy to succeed him as benevolent dictator.
In either case, the trouble with a pile of forks is people start wasting time with divided efforts, porting patches back and forth between forks, and infighting.
Hopefully one project becomes dominant, but it's not assured, and there's a risk of long term fragmentation.
Establishing something before he leaves is far preferable.
Honestly it's kind of a monarchy. And that makes his approach dangerous.
There's a benevolent overlord (King) who rules for life. And while the King is strong everything is pretty stable.
But the moment the King is gone you either have a strong designated heir lined up, or there's a succession crisis. And that leads to all sort of complications up to and including a civil war (fork).
The fact is that Linus is still King, and if he needs to designate a successor. Either the next King, or a Debian style election system.
My guess is he's thinking something Debian-like after him, because there's no one else with the cred to be dictator for life, and a more Democratic Debian style system is the only thing that could undercut his current authority.
Never rule out that there is a successor that he has in his mind but it's in a sealed envelope and the successor don't have a clue that he's the successor.
