To give a sense of how accurate that estimate is, consider this reference:
"In other words, the human body sends 11 million bits per second to the brain for processing, yet the conscious mind seems to be able to process only 50 bits per second."
That doesn't sound accurate. The human eye's resolution is in the tens if not hundreds of megapixels [1] with high sensitivity (meaning the compression isn't very lossy so the bits of information remain). Even if you assume only a few frames per second that's far more than 11 megabit/s.
Human vision is more complicated than that, there is some "compression" happening at the eye. But yes, it's almost certainly more than 11 megabits, more likely around a few dozen just for the eyes: https://link.springer.com/chapter/10.1007/978-3-642-04954-5_...
I am very suspicious of the numbers and statistics quoted in this article, as there are no references cited for their claims, and no indication as to how they arrived at them.
