This is amazing, we evolved the alphabet from pictograms to highly stylized characters to letters and now we're going full circle by incorporating emojis such as 🐂 that thousands of years earlier became "a" and 🐟 that became "d"
@szbalint just a small correction, proto-sinaitic is not a picographic script, it's an abjad script (only consonants are represented) like arab and hebrew.
Pictograms are images that represent ideas, not words (this is also why languages like Chinese aren't pictographic either!). A pictographic script would be the one the Aztecs used, for example. A lot of people misunderstand what they are, and I get it, but hopefully at least one more person won't make this mistake again.
