Passage Summary: Using tech makes our lives easier physically, but it makes us reliant on machines and power grids, which means we aren't self-sufficient anymore. Therefore, tech is actually bad for our well-being.

Conclusion: Modern technology reduces the overall well-being of its users.

Reasoning: Technology makes people dependent on complex energy systems and reduces their self-sufficiency by relieving them of physical labor.

Analysis: The columnist makes a significant leap from a 'loss of self-sufficiency' to 'diminished well-being.' For this argument to hold, there must be an unstated connection between these two concepts. We need to assume that losing self-sufficiency is actually a negative thing for one's overall well-being. Look for an answer that bridges this gap, perhaps by stating that well-being depends, at least in part, on being self-sufficient.
