For me, Technology is using our knowledge and resources, in order to cater to our need and wants, but not our greed. It eases our life, for eg. match stick is a technological solution to our discovery of fire, ages back, a fan is the same. But similar application has also further lead to coal power/mining and ACs, which in turn is catering to more of our greed and exploitation of resources and environment. However, with the advent, the current trend of technology is catering to a problem with another problem, the immediate example I can think of model of incineration plants to treat waste. Can we look at technology more need centric rather than greed centric?
