Things like this: "No native English speaker would ever think to try “Greco Unification” and consolidate the English, Russian, German, Swedish, Greek, and other European languages’ alphabets into a single alphabet."
The author probably ignores that different European languages used different alphabet scripts until very recently. For example, Gothic and other different script were used in lots of books.
I have old books that take something like a week to be able to read fast, and they are in German!.
But it was chaos and it unified into a single script. Today you open any book, Greek, Russian, English or German and they all use the same standard script, although they include different glyphs. There is a convention for every symbol. In cyrilic you see an "A" and a "a".
In fact, any scientific or technical book includes Greek letters as something normal.
It should also be pointed out that latin characters are not latin, but modified latin. E.g Lower case letters did not exist on Roman's empire. It were included by other languages and "unified".
Abut CJK, I am not an expert but I had lived on China, Japan and Korea, and in my opinion it has been pushed by the Governments of those countries because it has lots of practical value for those countries.
Learning Chinese characters is difficult enough. If they don't simplify it people just won't use it, when they can use Hangul or kana. With smartphones and tablets people there are not hand writing Chinese anymore.
It makes no sense to name yourself with characters nobody can remember.
