> Aboriginals had no writing system so there would be no keyboards.
Mesoamerica had at least one family of complete writing systems (I'll call this Maya, although whether or not they invented it or adapted it from others is debated), and another proto-writing system that may well evolved into a full writing system (the Aztecs, who at the time of contact appear to have been in the early stages of planning a conquest of the Maya). Andean cultures had a maybe-it's-a-writing-system-unlike-any-other, the quipus.
Of course, positing a less domineering conquest, it is very likely that cultures may well have developed their own indigenous writing systems via contact with Europeans--that is precisely what the Cherokee did. I doubt they would have stubbornly refused to pick up any writing systems.
> That should be a signal as to how 'far apart' colonialists and aboriginals were with respect to development of cultural institutions.
Yeah, Tenochtitlan had public zoos and museums, organized anthropology, universal primary education, ethnic quarters, professional sports leagues at a time when all of those concepts would take another few centuries to be 'invented' in Europe.
Oh, wait, were you suggesting that it was the Americas that was culturally backward?
> The writing you see in this post is invented by a Canadian-English Methodist Priest in the mid 10th century for the benefit of the aboriginals. The system, in current terms is itself 'firmly colonialist' (I'm sure someone will cynically characterize it as a form of oppression).
My understanding is that the modern indigenous groups see the use of the syllabics as less oppressive than being forced to use Latin, as the syllabics are designed to more closely match the language than using the Latin script.
