There is definitely a ton of value to be had from learning on the internet. Watching a 2 hour 92nd street Y debate on Youtube can be just as enlightening as reading a great book. But I still think books have a certain staying power due to their format.

The rigor of longform reading is still something special. I know I am prone to over-quoting from Thoreau, but as he said, "What is taken as argument in the auditorium is too often later found to be rhetoric in the study."
