@stux technically, yes - since autocorrect/typing-prompts which adapt to your personal idiom qualify, and there are probably genuinely helpful system-level things like dynamically-adapting network-connectivity code.
But "no" to the question in the sense that you probably intended it - large-scale or intrusive user-facing apps.
@stux or - as others have pointed out - camera auto-focus is perfectly great and worthwhile to me, though I wouldn't want "auto-touchup"
