A modern programming language that makes developers happier.

kotlinlang

hi guys
i'm following your conversation since the beginning
so here are my 2 cents
making classes `final` by default is a good idea
we are all lazy programmers
so in java, we skip `final` by default because it's easier
just as in kotlin, we skip `open` because it's easier
however, what does it really achieves?
not much in the end
that means that it'll need extra effort when you want to subclass
(as opposite of needing extra effort when you don't want to subclass)
in most use-cases, that's just bikeshedding (<https://en.wiktionary.org/wiki/bikeshedding>)
because it has zero consequences for application developers
only for some (not most) frameworks
as for the argument of retro-compatibility, that we are now 1.0
guys, do you imagine many use-cases where changing the default would cause a major issue?
i don't think major companies have already developed their information system in kotlin
sorry for being pragmatic :simple_smile:
