Ruby is fairly easy to learn. Does that mean it has a nearly empty toolbox? No it doesn't.
A language with a GC is easier to learn than one without a GC. Does the one with a GC have less in the toolbox? What if it also allows opting out of GC?
ObjC is considered a hard language to learn, esp for people used to C++ and Java. Does this come from it having more tools in the toolbox?
"A language with a short learning curve is like a toolbox that’s nearly empty" is a nice quote, but it also objectively seems to be wrong.
