This analysis and comparison to ancient glyphs completely overlooks how emojis are tied in to technology manufacturers and therefore their profit interests. Emojis have been a major driver of the planned obsolescence business model. iOS (and even Android before version 12) requires a full operating system update if you want to get the newer emojis; eventually, that means having to buy a new Apple device. The constant addition of new emojis (and their essential role in social media) is one of the many pressure points that Apple uses to get their existing users to buy new devices.
