Henry David Thoreau's writings about self-reliance are harder to tolerate once you learn that he was supported by family. Yes he lived in the woods, but his mother literally brought him food. In the same vein, Wendell Berry's writings about technology are harder to tolerate once you learn that he made his wife type up his manuscripts for him to be sent on to publishers.
It's worth having deep conversations about the impact and value of technology in modern society. It's also hard to take a sermon seriously when it's being preached by a hypocritical curmudgeon.
