10/03/2019, 2:22 PMwhy not? I don't feel a need for Kotlin-like nullability in a language with Optional as a first-class citizen, e.g. in Scala.

10/03/2019, 2:28 PMin C# and Java this is problematic because these languages were designed without safe nullability model, now they both try to solve it somehow.
C# goes Kotlin way (in C# 8.0 you have nullable reference types)

10/03/2019, 2:30 PMthat's kinda my question, why didn't they go with nullability in the first place, since to me it's obvious choice, unless there are big downsides

10/03/2019, 2:35 PMold languages like Java and C# I think because it was not obvious that time that nulls will make so much trouble. There are many similar examples for things that were not obvious 10 - 20 years ago (say, Java creators argued that lambdas are not needed).
For modern languages I have no idea... even if it is costly to introduce, seems like we learned nothing in the last 20 years...
