What is the Butterfly Effect? Here is a simple explanation!

If you make a small change to a complex system, the consequence could be quite chaotic. This is where comes the allegory of a butterfly flapping its wings and causing a typhoon.

Indeed, complex systems are very sensitive to small changes. You should be very careful, for example, when building a domino chain, when pushing a small domino piece can ruin the entire row. The 2020 COVID-19 pandemic is also a perfect example of the butterfly effect: one Chinese guy ate a bat, and the virus jumped on to the humans, causing millions of infected people and 1.5 million dead.
