I understand your point, but a slightly more positive reading might be that the quantity of information consumed, while perhaps unable to be precisely quantified, can be related to the type of content being perceived.

Staring at wall produces little information in and of itself, perhaps through reflection, but staring at a TV produces a load of information, most of which is useless like names of characters, their favorite dresses, what food is being eaten where, etc. You can learn a lot by just passively observing even "dumb" TV especially if it contains foreign content or skills like cooking or sports. Again, not saying all of it is relevant to your life, but that's a different issue.
