World's Most Complicated Writing System (corrections in the description)

CORRECTIONS:
1: The Thai writing system has actually changed way more than I thought. I still think this is a good overview of why it's as complicated as it is, but Thai people can't actually still read stuff that's super old. Please disregard that lengthy, passionate speech at the end about how their writing system connects them to their ancient past.
2: Like I said, there are plenty of writing systems I didn't know about, and NativLang makes a very good case that the Tibetan writing system is actually the most complicated: https://www.youtube.com/watch?v=btn0-Vce5ug
3: "Vocalized" is not what I ment. The word I should have used is "voiced." "Vocalized" means something different.
