An archaeologist can describe an attempt to revive Mayan numerals as
tourism-inspired. However, he cannot prove it, even tho it occurs in
the neighbourhood of places of interest. There is even an argument
that it could be inspired by anti-tourism, a desire to use a system
unintelligible and prior to the outside world. It would also seem
somewhat unjust and arrogant of such an academic professional to
totally rule out the possibility of a genuine and scolarly interest
of the native people in their local semiotic history.
What is said about alphabets is relevant (the customary English word
for 'On-Topic') to alphabets.
The 'tourism-inspired' allegation, apart from being
unproven/unprovable, is unfair and highly 'loaded.' It is unfair
partly because tourism is a typical and likely rare source of income
for peoples governed from elsewhere, many of whom have experienced
alphabet suppression. It is loaded because it carries with it an
unstated but inevitable connotation of pecuniary motivation, which is
like a trial without a case for the defence, and a prosecution
consisting of hard-to-resist innuendo.
A professional in the field should not be brought to book for every
off-the-cuff remark, but when that remark is quoted and and broadcast
more widely, it required an answer.
I hope these few lines have clarified the relevance of politics,
including those of Empire and Academe, to the use of alphabets and
sign systems, in case anyone was in any genuine doubt.
