Immutable does not mean “not changing”, but rather that you don’t have the rights to change. If you take the immutable option away, then its changing again, like when you update your system. People who have a problem with the term say, “see its not immutable, the term is a lie!”. Which I kind of agree, but somewhat conflicted.
Atomic is an attempt to create a new “meaning” with a word, that cannot be misunderstood. Its trying to avoid the situation of “Free” in example. But I don’t like the term Atomic either, because it just suggest to me that everything is split into many little parts and is not self explanatory like Immutable. I’m conflicted here too.
I’m always conflicted.
