> Haskell is simple even if unfamiliar to you. Brainfuck is complex even if familiar to you.
I would actually swap these two descriptions. Haskell is complex, because it has many "complications" (in the sense of features). But those complications permit simple programs. Brainfuck is simple, it has few complications (only 8 instructions) but this forces complications into the programs written in it.
Simplicity is not merely measured in the "number of things" you have, it's contextual. Otherwise we'd all be writing in binary representations because base two is the simplest way to communicate information.
Simplicity is also "how many things" it takes to express an idea or do a useful thing.
In many ways, written Chinese is simpler than written English.
