Ouch. Ambient sounds of the forest are a lot better than the modern equivalent of loud neighbors and drilling. He also seems to have forgotten that humans built fires. Caves have great sound insulation and I'm pretty sure our ancestors knew how to choose their caves.

I have spent years being a sleep deprived student because the dorms were super noisy with random parties and paper thin walls so I really can't relate to the implied utter comfortable sleeping habits of modern people. I'm sure there are people complaining about noise pollution in NY as well.

No one in my circle sleeps on an overpriced mattress. Mostly it's just the bed the place that we rent has. I never could connect with articles implying modern people live in these utterly comfortable utopias when it's really not the case. People are depressed. Especially males are doing horribly.
