Imho, while there are lot of people suffering from anxiety and stress these days, it has a lot more to do with info overload than info deprivation (which is what isolation does to the chimp brain).
I would argue that it's also more likely because it's more easily documented than it was ever before. Personally I feel like this is what happens when you create a culture where people always feel like they're not doing enough and can constantly see what other people are doing that they aren't.
