It's not that simple ... these “instant answers” come from engines like ddg ... sometimes ddg has a text (generated by an AI) ... but sometimes ddg only has an excerpt from wikipedia ... and for wikipedia we already have the infobox, whose content we get directly from wikipedia ourselves. DDG was just an example, other engines also provide “instant answers” ... we would have to modfy all these engines and try to recognize wikipedia excerpts in order not to add them to the answer box.

But I agree with you, this duplication bothers me too.
