That's super interesting, and a funny personal story, thanks for sharing!
A lot of the time I actually just guess what word something is based on length and context
I mean, as far as I know that, plus the rough shape/outline of each word, is how fast non-dyslexic readers read in general, at least for common words, haha. Actually reading letter-by-letter is relatively rare
Okay, but the economics of doing that are different between software and hardware. It's much more expensive to have a full second hardware design compared to just turning a software feature off in certain markets.
