Many people dream to make it as indie, most don't even achieve that.
No it isn't, there are now two versions of Minecraft, the classical one, and Minecraft Bedrock, that is the one written in C++.
Minecraft Bedrock doesn't have half of the community that Minecraft classical enjoys, hence why Microsoft is trying to use JavaScript based extensions to bring the mod community into Minecraft Bedrock.
Finally without Minecraft classical market success, there wouldn't exist Minecraft Bedrock at all, so Java did serve well enough to Notch's fortunes.
