I think he's very much aiming at simplicity. Btw, the essence of Scala really is simple. Take for example DOT (Dependent Object Types is the theoretical calculus Scala is based on), it is simple https://www.scala-lang.org/blog/2016/02/03/essence-of-scala.html https://www.scala-lang.org/blog/2016/02/03/essence-of-scala.... as video https://www.youtube.com/watch?v=bZEWNKzhBoU https://www.youtube.com/watch?v=bZEWNKzhBoU Or take his emphasis on simplicity in practical software engineering: https://www.youtube.com/watch?v=-qf8yteuxPs&pp=ygUObWFydGluIG9kZXJza3k%3D https://www.youtube.com/watch?v=-qf8yteuxPs&pp=ygUObWFydGluI... Than there is the question of practical concerns with Scala, like fitting onto the JVM, interoperability with Java, superficial features for programmer comfort (or lack thereof) and the tendency of some people to use the most powerful features for the simplest of problems that inevitably lead to messy codebases. And that certainly makes things complicated. > the notion of "object-functional" itself, as a hybrid concept, lacks simplicity I think this is misunderstanding about what Scala is all about. Scala is not supposed to be 50% functional and 50% object-oriented. It's supposed to be both 100% functional and 100% object-oriented (aka having powerful module system) _at the same time_. It's supposed to be a concrete proof that this dichotomy (FP vs OOP) is false and you can have both in the same language with the same features. This is contrary to other languages which may have support for FP and OOP but have _separate_ support for each, like SML, OCaml or F#. Scala is in this tradition, but different, it supports FP and OOP with one set of features. And from this point of view it is _simpler_. Whether people find it _easy_ is another question.
