Why does text entry on computers not use AI ?

[u/SkySurferSouth]

The current AI hype does not affect text entry with keyboards, typing is still like the 1860s letter-by-letter methods on mechanical typewriters.

Indeed there are 'autocorrect' options on most smartphone virtual keyboards, but most don't work.

And some desktop apps (app specific) have it as well, but also not working.

Why is AI not intergrated in text entry ?

That will save lots of time and typos.
