It&#x27;s almost certainly not economically efficient for a software engineer to be darning their own socks. Economic efficiency doesn&#x27;t align perfectly with resource or energy efficiency in an environmental sense but in this example it is still likely true.<p>There are economic and environmental costs to everyone having the tools, skills and supplies to repair a reasonable range of products. At the least it likely makes more sense to have a specialist perform any but the most basic repairs rather than doing it yourself.<p>In some cases repairs make sense from an efficiency perspective, in some they don&#x27;t. All I&#x27;m really saying is that it&#x27;s better to evaluate the more efficient choice dispassionately rather than painting repair as somehow morally superior to buying new.
