Just glancing over the article, I spot a problem... "Indeed, it's regrettable that we failed to evolve an ideal set of fingers to help us come up with numbering system suitable for counting and calculating. Instead, with our 10 fingers, we are stuck with the clunky decimal system." That's not true - we have a great set of hands for counting to twelve, or at least one as good as counting to ten. Just use your thumb to count the "segments" of the finger-bones. I heard that this is how the Babylonians did it. They certainly managed to get by with a base-12 system.
