I am not a high tech computer person. I am low tech..(even lower tech than @Zorba in some ways) so please explain like you would a kid. I am trying to understand what they are for. I understand they are bought and sold as a commodity. But I do not understand why I'd want to own one. I understand that there is some people linking them to a digital ticket...like to get into a movie or a beer festival. That makes sense to me...it's a tangible something. But there are also NFTs of a tweet. Does that come with licensing features like music? Or is it more like a piece of artwork that some may find valuable and others not simply because of niche interest?
