It is not a duplicate, but based on its description it overlaps heavily with several sites including cstheory:

>Proposed Q&A site for computer Science practitioners, **researchers**, and CS students interested **in** topics like **theoretical computer science**, artificial intelligence, programming language design, digital logic, or any other area of CS not directly related to programming. 

So IMO it should be closed (or alternatively modify the scope so it does not overlap with existing ones).
