This is another way of saying "it's too complicated".

The purpose of the advancement of technology is to make things easier. The practical use of these languages is to create something that makes money, with as little overhead as possible. A language should be selected to make things easier, with little overhead. Not being able to easily scale to 100 people is a very bad business decision, especially when the same functionality could be achieved in languages/methods that require less education (cheaper) and have a larger talent pool (cheaper). I'm talking about the use of tools that are meant for productivity, in general, not Scala.

It's a more precise way of saying it's too complicated. You should be precise if you want to solve issues.

> methods that require less education (cheaper)

This is not a good thing. Trying to devalue a skill is just asking for trouble, especially in engineering.
