Again, this here is not about Skookum good or bad, its about the OP trying to make a course about it.
Additionally, replace with Blueprints and you could say the same. Though Blueprints can now be nativized finally, it wasnt that way until 4.16 i guess. And Blueprints are interpreted with their own Intermediate Bytecode similar to C# or Java. Actually the same VM integration as it was with UE3 and UnrealScript. C++ will always be more reliable and faster than any higher level scripting language. But implementation can be much faster and easier with scripting instead of coding C++.
I am asking again, why so hostile against ? If you dont like, say it one time and dont use it, but right now you seem to be on a personal crusade against it.
