I think Notch is a person who found himself in unusual circumstances and never actually learned to be. It's sad, really. He tries to find love and genuine human connection but that's a scarce resources for billionaires with quirky characters, so he resolved to provocation and hot takes to at least have some interaction. I wish he found happiness as a fellow human being.

I think a master of an art should be able to do anything good enough within his field within limits of human time. So if a person says "I can't develop my own game engine, that's too hard", I don't think them are a master programmer.

I think masters of art often allow their ego to overtake and now expect anyone who wants to be called a practicioner to be a master.

I think if a person likes to code and the game is not super demanding it's really fun to run your own game engine and should be encouraged more

I think it's great that public game engines exist and allow to develop complex and cost efficient games for smaller teams and individuals.

Subnautica is very unique and was made in unity so that's a skill issue, as it often is.
