Awesome talk, thanks Kotlin looks amazing comparing to Java, and as C# lover it looks great too. One thing I likes more in C# is the async/await syntax and async programming style. Kotlin's answer to that seems too complicated and also longer.
Unfortunately is not a good reference. He's lacking skills and experience in any of these languages. ... 27:52 why c# construct and init with property, but kotlin version use construct... it's not relevant ,don't watch this, better immediately jamp into basic kotlin course
