Indeed. It's C# that makes me like Kotlin so much. I was trained in Java but used C# in a fully-professional setting for longer. C# as a language make a lot of very smart decisions that Kotlin took into itself when being created and out if it comes a non-Microsoft-owned (which matters for some people), comfortable, powerful language.

If I had to switch and use C# as my main work language for a company, I would be perfectly happy to.
