I don't know if it's correct to say that Vulcan culture is unaffectionate, just thay they don't express affection in the way you are used to. Remember: Spock was played the way he was in the 1960s to demonstrate the distance humans are willing to go to tolerate other cultures, no matter how (literally in this case) alien.
There's definitely a lot to unpack in suggesting that their culture deserves to "fail" because they do not assimilate (lol) into your culture.
I agree with you completely. No disrespect to Mint, but immutability is (IMO) possibly the most important advancement for Linux adoption in its entire history. I would love to see more distros release immutable versions.
