You have to look at the longer term with technology, so far it's been an overwhelmingly positive force for humanity. I personally think it's the greatest thing ever, but we may one day invent the thing that ends us. Maybe that's AI, maybe we unlock a power in the physical world that we can't be trusted with. For example if anyone could build antimatter bombs in the garage, terrorists or other discontents would have used it to end civilization. There's no law of nature that says great power must always be hard to come by, and I wonder if that's not the answer to the Fermi paradox. Civilization might be a short-term blip, an unstable state on cosmic timescales. H.G. Wells ends the Time Machine with: "for the question had been discussed among us long before the Time Machine was made - thought but cheerlessly of the Advancement of Mankind, and saw in the growing pile of civilization only a foolish heaping that must inevitably fall back upon and destroy its makers in the end. If that is so, it remains for us to live as though it were not so."
