There might be some confusion about the transition to what some call post-literate era: era where text is not the primary medium. That’s not necessarily bad because you get the advantages of other mediums - oral and visual but it is something to keep in mind.

I'm bit skeptical that a post-literate era is happening. I gather it appears in some sci-fi but I don't see much sign in reality. I mean here we are on a text only site. If anything we seem to be heading for a 100% literate society. Literacy graphs here: https://ourworldindata.org/grapher/cross-country-literacy-ra...

I don’t think the post-illiterate era means that text will disappear. I think it’s just not going to be dominant anymore but I also have my reservations since I do prefer the text medium.
