Wrong, David. 
Turing completeness means that anything you can *COMPUTE* in one
language you can computer in another. Python, Lisp, C++, etc.
are all equivalent in that sense. 

But you can't *DO* all of the same things in all languages -- for
example: you can write a device driver in a language if you can't
specify interrupt vectors or hardware address pointers.
