Going to have to argue the other direction...
First on the Input/ knowledge gain: 100 - 150 wpm is roughly what people speak at, versus average reading speed of 200 to 250 wpm all the way up to 1000 wpm for top speed readers. If we were to analyze straight by wpm you can put into you Reading is 2X-10X better... Not that it's even a good argument though.
Books take a long time to create because the information is curated. The author of the article makes a decent point that people should focus on great books... and the answer there is yea... they should focus on great books over listening to podcasts. And yes ... there are a lot of good books out there.
