Because they failed to implement a GC that didn't crash all the time, as the Apple forums used to testify before ARC was touted as the best thing since sliced bread.

The wonders of mixing Objective-C libraries compiled in mixed mode.

The mixed nature of Objective-C.

With @ and [] one is in Smalltalk land. Without them, one is in C world.

> Java is a statically typed language, and does not have a 'dynamic world'.

Yes it has, via reflection, annotations and dynamic bytecode generation.

This is an odd and not particularly true way of looking at things. [] (for message sending), is merely some syntactic sugar for the objc_msgsnd function call.

Which could have been implemented in a better way, e.g. Dylan does dynamic dispatch with multi-methods without requiring me to type [] everywhere. A real pain in non US keyboards.

Also Dynamic casts(w/exceptions) and virtual methods/Dynamic dispatch which do provide some dynamicity not easy/natural in c.
