This does not appear to me at all to be the point of the article.  The
point of the article seems to be that the Julia benchmarks compare
unfairly the performance of Python to Julia, because they do not use
algorithms that suit "the best way to use Python."  But I have to
agree with bartc, that is not at all the point of the benchmarks.  The
point of the benchmarks is to compare the performance of a particular
algorithm or set of algorithms across a variety of languages.

It's fine to say that this method of computing Fibonacci sequences is
inefficient; but anyone who's spent any time on the problem knows that
recursive function calls is not the most efficient way to calculate
them in most languages.  So it must follow logically that the point of
the benchmark is not to prove that Julia is faster than Python at
solving Fibonacci sequences, but rather that Julia is faster than
Python at solving the class of problems that would be implemented in a
similar manner as this particular implementation of Fibonacci
sequences.

No other interpretation makes any sense.  And if that is the point, as
logic dictates, then comparing the performance of algorithm A
implemented in language X to the performance of a completely different
algorithm B in language Y is generally both misleading and pointless.

If you can prove that A is the most efficient alogorithm possible in X
and B is the most efficient algorithm in Y, for solving the same
problem, then and only then, you might have something.  Otherwise, I
think what you're saying is bunk.
