"For me, personally, I think I started to see how the territorial acknowledgement could become very superficial and also how it sort of fetishizes these actual tangible, concrete treaties. They're not metaphors — they're real institutions, and for us to write and recite a territorial acknowledgement that sort of obscures that fact, I think we do a disservice to that treaty and to those nations."

how to count!

back to basics 🤓

the normal way

    1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, …

"Decimal"

"Base 10"

the normal way

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, …

"Decimal"

"Base 10"

first weird thing: from now on, we will start counting at zero

the normal way

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, …
