Well, will be interesting to see how Dotty plays out.

DOT may have been proven sound, but compilers are complex beasts; implementing DOT while preserving an upgrade path for Scala will likely be both difficult and limiting (since Dotty will inevitably be shackled by Scala's past).

For now we've got Scala though, in a couple of years maybe Dotty.

Dotty will inevitably implement the same features with the same fundamental issues. This is not about some old stuff we all regret having in Scala, this is about new low-quality proposals. When they get rubberstamped, they will end up in both Scala and Dotty.
