Being able to easily, and quickly read scientific literature is not a universal trait. You're in the top 1% (probably top 0.1%?) if you're able to do that and actually understand the source material.
The average person has a hard time reading and fully understanding a newspaper article or cooking instructions on a pre-prepared meal.
The first paragraph is fine -- I agree. The second paragraph is a silly hyperbole that comes up over and over again on HN and needs to die. Major newspapers are written for about 8th grade level reading comprehension. Cooking instructions on a prep'd meal are probably much lower -- maybe 5th grade. The "average person" (whatever that term means) living in highly developed nations can read at 8th grade level or above.
