A lot of people are functionally illiterate. Those people are online now. We have image, video, and sound based social media for them. They send each other videos and voice messages instead of texts.

Not only that, they're creating content for each other. People who can barely compose an email run TikTok accounts and YouTube channels and podcasts with audiences in the millions.

I don't even know if I think this is a bad thing. Sure, their education system failed them, but they need to know how to do things, and they often have information worth sharing. Providing video tutorials almost becomes a question of accessibility (in the a11y sense) in some contexts.
