10 as the first overflow of digits is not a clear vlaue, it depends on the notation because its base is unclear.
Ten as the English word is 100% defined. The issue is we translate seamlessly between the word and number, but there really is no confusion when writing ten. 10 in hex has a different english word: sixteen.
English number names are mostly decimal-based, but their values are still fixed. Ten isn’t the word for “the first time our number system overflows”, it’s an amount.
So I disagree. Ten will always be (…) this many, because it’s an English word.
