Where does this magical 17.7% number come from, which leads you to think that Bitcoin will need “70 years to reach everyone-scale”?

You link to Pieter’s draft BIP which states “The growth rate of 17.7% growth per year is consistent with the average growth rate of bandwidth the last years” yet the draft does not provide a source or citation for this number.

The same number is used in Luke-Jr’s proposal… “if we assume a 17.7% rate of technological improvement” (https://github.com/luke-jr/bips/blob/bip-blksize/bip-blksize.mediawiki) yet once again there is no source or citation for this number.

So where does this magic number come from? A study? What period did it cover? What was being measured? Home broadband connections? Submarine cable capacity? How do we know this number is even relevant to Bitcoin scaling?
