humans aren't perfect. we are subject to make mistakes and will make many. i thought that over all, this was a very interesting movie. it showed that not everything we do is perfect and can fail. i also learned that there are many causes of structural failure including time and nature.more of these causes include rust, weight, and water. materials are also very important as if they are too heavy or too light the creation might fail and break. if you tried to build a bridge for cars out of plywood, it would not work out very well for you. The video also talked about how failure is necessary for success as we have to learn from our mistakes. thankfully technology has advanced enough that we have very accurate simulations we can run to test our creations before they endanger human life.
