Read Michael Pollan's "In Defense of Food" for a more nuanced look at the relationship between "technology" and food. One of the reasons "food" is becoming cheaper is due to eliminating much of the nutrition and through ignoring the externalities of environmental costs.

The improvements in health care seem to be offset more and more by our poor food, sedentary lifestyles, and fractured relationships.

Maybe technology has made it cheaper to build a house, but that seems a wash as the dominant cost of housing is the property on which it is built.

In general, yes, technology improves our lives. But can not solve every problem in and of itself, and can exacerbate underlying problems if misused.
