Seriously? Typing on glass without auto-correct is painful. Do you really think it was a bad idea for designers to design that feature?
And you think that is the right call for the majority of people?
Also, in addition to auto correcting words, your phone also auto corrects individual key presses based on the word you are typing. The same physical impact on your screen will register a different letter based on the letters that come before it.
So part of your “typing on glass accuracy” is dependent on a designer designing that feature that “does work ahead of time”.
No. Certainly not on a desktop, where I type much faster than any suggestion can appear (esp. infuriating on IDEs); usually not on a phone either, where "corrections", while sometimes faster than me, are always wrong.
