This is always the response to any hint that technology isn't the greatest thing ever. But it's like a no-op. The questions that it leaves open: 1. Were the people saying it earlier wrong? 3. Assuming they were wrong, is there any reason to suspect that their wrongness has any relationship with the wrongness of people questioning the effects of a different technology hundreds of years later?
