  This note is a contribution to the debate about the optimal algorithm for
Economic Complexity that recently appeared on ArXiv [1, 2] . The authors of [2]
eventually agree that the ECI+ algorithm [1] consists just in a renaming of the
Fitness algorithm we introduced in 2012, as we explicitly showed in [3].
However, they omit any comment on the fact that their extensive numerical tests
claimed to demonstrate that the same algorithm works well if they name it ECI+,
but not if its name is Fitness. They should realize that this eliminates any
credibility to their numerical methods and therefore also to their new
analysis, in which they consider many algorithms [2]. Since by their own
admission the best algorithm is the Fitness one, their new claim became that
the search for the best algorithm is pointless and all algorithms are alike.
This is exactly the opposite of what they claimed a few days ago and it does
not deserve much comments. After these clarifications we also present a
constructive analysis of the status of Economic Complexity, its algorithms, its
successes and its perspectives. For us the discussion closes here, we will not
reply to further comments.
