Note-taking may not seem like a popular thing to do right now especially because of high-tech gadgets that people use instead. There are some people who still love basing what they should learn through notes. Note-taking during meetings or in presentations will allow you to write down information that you may forget later on.
It is very likely that you would need the information after some time. You would like to be prepared otherwise, you may have to do your own research that may not be connected to what you have witnessed or head from the presentation. Note-taking will help you remember the details that are essential for your tasks and responsibilities.
