There is quite alot of differing philosophies or opinions on how to treat wisdom teeth.
In general, I have an educated conversation about the pros/cons of both sides.
By looking at your panoramic x-ray, it appears that your bottom wisdom teeth will never fully erupt. This can cause problems occasionally in terms of having infections around the gums of the wisdom teeth (pericornitis). This occurs because food, bacteria, and plaque is trapped underneath the gums of wisdom teeth that are not fully erupted. As well, wisdom teeth are often hard to clean because of their location in the mouth. Without flossing and brushing properly between the wisdom tooth and the tooth in front of it, cavities can often form on either teeth. Those are the most common risks of leaving the wisdom teeth in place.
The pros of taking out the wisdom teeth now is that you are younger, and your body has a better healing capacity. Some people also prefer to have the wisdom teeth out before they become a problem. While it is possible to have the wisdom teeth be asymptomatic, there is always a risk that they will become a problem in the future.
Educating the patient on this, they are able to make an informed decision themselves on what they would like to do. Hope that helps!
PS. You have an extra wisdom tooth on the upper right!
