But over the years, as I have thought about these technologies and the things that I work on, a question kind of nags in the back of my mind, which is, what if we're wrong about the virtues of technology, and if it sometimes actively hurts the communities that we're intending to help?
而多年以来，我常常想到 这些科技 以及我所做的这些事情， 有个问题一直让我耿耿于怀。 我们有没有可能高估了科技的好处， 会不会有些技术实际上伤害了 我们想去帮助的群体？
