Let we remember that Smalltalk was designed for a kids, so "programming
is hard anyway" is in my opinion just too simplified answer.

While teaching new Smalltalkers I noticed that those without any
programming experience got it faster, specially comparing to those with
a relational DB experience. Who were and are still part of mainstream.

So, maybe it is better to say that established habits and mental models
in programmers heads never changed enough to get OO right?

To rephrase a bit differently: Hardly anyone is playing OO right because
OO was used too long on top of relational world and the ideas of pure OO
were forgotten and lost.
