Can there really be a bad programming language In terms of functionality and execution

Answer 1

P... Prolog... ><

Answer 2

I'd rather say that it's more about inadequacy, than being "bad". A programming language is always thought as a way of human-machine communication. A language can become outdated and eventually extinct, but in the days of its glory it is used for some particular functionality, particular set of machine types or particular type of a problem.

Answer 3

yes if the design and execution is really screwed up
