Anecdotal counterargument: I am a visual learner. For almost all topics I learn about, watching a video is by far the most effective, fastest, and most impactful way for me to grasp and remember new concepts. A very large part of my education in math, science, machine learning, music theory, filmmaking, screenwriting, visual effects, history, and chemistry was video lectures/essays/content.

I agree that the famous "three/four types of learners, everyone belongs to one of them" factoid isn't true, but disagree that "No one is a 'visual learner.'" I am a visual learner.
