I think this is just a matter of the point of view and the historical background of each one.

I have read some reviews from C++ coders coming from C4 or Torque and they find Unity quite easy.

I programmed a lot of business tools in my past (Delphi, PHP, C++, Java). And I like C# much more than a limited scripting language. And since I bought lots of components for my business projects, I am also used to a components approach. It indeed differs a bit in Unity, it is not the same like in Delphi for example, but the idea is the same and integration in a project is just drag and drop in the end.
I know from experience that components are a very good approach for rapid application development. I can plugin new technology very fast this way without losing my existing solutions. And I can even exchange such components against new versions without adapting a single line of code.

From my point of view this is absolutely a future technology.
