Ok I understand how the AI got this one wrong. You can make a "glue" by mixing flour and water together. You can also thicken a sauce by adding flour. So the AI just jumbled it all up into this. In its dataset, it's got "flour + water = non toxic glue". However, adding flour to a sauce, which contains water, also thickens the sauce. So in the AI's world, this makes perfect sense. Adding the"non toxic glue" to the sauce will make it thicker.

This just shows how unintelligent so called "Artificial Intelligence" actually is. It reasons like a toddler. It can't actually think for itself, all it can do is try link things that it thinks are relevant to the query from it's dataset.
