Our use of internal combustion engines to generate power is driving global warming through the emission of carbon dioxide. The modern weapons of war take a high toll on our environment. The critique of technology is myopic though, if it doesn't also enumerate the many benefits of better food production, better health care, better methods of transportation and communication which have improved our lives. Imagine what old age would be like without the assortment of medicines which manage medical conditions such as diabetes and heart disease. The ability to replace a joint can greatly improve quality of life.
Technology is a tool no better or worse than the person who uses it.
A shovel can be used for landscaping or as a weapon for murder. Factory automation can be used to improve the quality and productivity of workers jobs or replace people with machines. This was an area of concern for me as a former manufacturing engineer. One of the reasons I wanted to get out of the world of engineering was because I saw our technical ability growing much faster than our ethics to guide its wise use. Rather than using my abilities to advance technology, I thought a better use would be in the ethical domain as a minister working to see technology used to serve the well being of people rather than exploit them.
