Why does autocorrect only work when you don't need it?

You type "okay." Autocorrect changes it to a word you've never used in your life. But when you're typing from the heart and genuinely need help... It goes completely silent. AI isn't trying to understand your feelings. It's calculating probabilities. It guesses what usually comes next based on patterns, not meaning. Sometimes it's brilliant. Sometimes it turns your deepest message into a punchline. It's a quick reminder that algorithmic prediction isn't human understanding. Not yet.
