My son does this all the time when we are in the middle of a deep discussion about history and politics and things that are happening in the news. It is like he has this energy that builds up when he has so many different interesting things in his head and needs to release it by talking. It is like he has a hyperactive mind but no attention deficit.
I constantly juggle thoughts about our family's medical issues, bills, homeschooling, our isolation problem, and things happening in the news while carrying on a conversations about completely different things with my husband and my son. My son can easily see when I am not paying total attention to what he is saying because he does this himself and he often tests me to see if I got what he was saying, but in addition to that he wants my opinion. I am usually able to tell him what he just told me but being able to formulate an opinion while juggling all the thoughts is more difficult. He is better at coming up with an opinion.
My son could also learn and carry on a conversation while playing computer games. In fact it seemed like he could pay more attention to me reading boring school things if I read to him while he played a game. He could always answer all the questions after I read to him. He is good at online games that require multitasking.
My adult daughter was always a fast learner. She has to manage multiple things at once to be good at her job in executive sales. She is a top performer because of her multitasking ability. People without excellent multitasking ability would not make it in her job.
My husband, in his job as a manager, has to multitask constantly to do his job well. His problem solving ability, outside the box thinking and ability to multitask well are the reason he got his latest promotion over people who had more education.
But I think there is a down side to my son's multitasking ability. His brain wants to keep multitasking all night long. He has trouble turning off and keeping off all of the channels.
