I’m not so sure it’s “at least as good” as sophisticated autocorrect. If you have a sufficiently advanced prediction model, it seems to me that you could make better guesses on context, which might, just by chance, outperform this approach. If you narrowed it down to only words that matches using this approach, but still used some kind of prediction based on context to pick which, I’d expect it to likely perform much better.
