I had read that some tribe in the Amazonian region speaks a language that lacks any number. So they would use "many" to describe more than say, 2 or 3 things. Hence for them, I suppose, 99 is the same as 100 essentially. There is no obvious way for their minds to distinguish between big quantities, since there is no obvious way to explain it in words. I would tend to think that their language isn't "Turing complete" in the sense that it cannot describe anything that is describable.
If we take English or any other language other than Russian, I had read that it is essentially impossible to translate Russian in the sense that the "true meaning" of what is being said, cannot be translated into English words. Hence, I would tend to think, English is also "Turing incomplete". The same holds true for any other languages, of course.
Does this mean that we are limited in our thoughts due to our languages? Can we change/improve our thoughts by creating new words and expressions and possibly grammatical rules?
