Sadly, AI makes adults less intelligent than a 4 yo, but they feel like geniuses.
One of the "results" was figured out almost half a century ago in commercial farming. But there are clearly "accepted" ways to do things (fish tank water > human urine for instance). I would guess 90+% of the researchers have never grown plants outside the lab, and therefore probably don't know how to make compost or other common practices (like how to fertilize plants with urine).
