The term "anti-literacy" is linked to laws in certain United States that made it illegal to teach slaves to read and write. The term needs to be revisited, updated, and re-implemented, as it describes people today who can read and write but don't want to. The new use of "anti-literacy" would likely be reserved to psychology studies but the term "anti-literate" would be a common and apt description of more and more people.
Historically, illiteracy is the norm. There are entire cultures even today who are, for all purposes, verbal communications only. It was mostly government that forced literacy on schoolchildren. An increasing segment of the population is reverting to a range between illiteracy and anti-literacy.
I see more and more podcasters and television talking heads whose speech gives away that they don't read and definitely don't write - and these are supposed professionals in the Communications Industry.
As the internet communications bandwidth increased, it has gotten harder to find a one-page info sheet on something, but instead I find 50 videos of varying length, quality, and questionable research by anti-literate wannabees.
The workplace is backsliding as well. With the prevalence of video meetings through mobile phones, the quality and quantity of clear, literate communications is declining.
I suspect that very soon we will see an "AI" autocorrect option for video makers, much like the autocorrect and autoformat functions in Microsoft Office applications.
It's already happening with profanity where the profane words are simply dropped out, but it could also be implemented with any other speech.
The video software will give the editor the option of accepting or rejecting any recommended changes, including "accept all changes" or "accept changes automatically".
The "AI" software could also change the mouth movements of the speaker.
It can be called "Autospeak", like Auto-TuneTM for music.
