During ramblings about new Minecraft jeb_ recently said that java is not going to be sunsetted, or at least that's what I understood.

Of course the course of Microsoft and jeb_ might be different and he might get pushed towards some decisions later. The problem is that kids nowadays don't use computers. They use phones and tablets. For me Minecraft experience on phone is awful but there are many young generations that consider it native way of playing games

Note that you can play Minecraft Java on Android with PojavLauncher: https://github.com/PojavLauncherTeam/PojavLauncher

Although I see now that the project is archived, not sure the story behind that.
