why do fire alarms go off when cooking?

Question

Are there actually dangerous levels of carbon monoxide from cooking? You would think fire alarms would be a bit smarter by now to distinguish someone cooking from a dangerous life-threatening situation.

fire alarms do not detect carbon monoxide, they typically detect smoke (detecting carbon monoxide and co2 also sometimes happens).

And when you burn your food there will be smoke.
