Technology is fine. It's what people do with it that makes it beneficial or harmful. We have had a handful of sociopaths, megalomaniacs and weaponizers of it.

“The most suitable apparatus for this purpose is that class of dynamo-electric machinery which employs intermittent currents,” Edison wrote. “The most effective of these are known as ‘alternating machines’ manufactured principally in this country by Geo. Westinghouse.”
Edison’s logic was twisted, barbaric and possibly brilliant: If he could convince the world that Westinghouse’s alternating current was a swift and efficient killer, his method would be seen as safer, increasing his market share.
“The electric chair’s midwife was greed,” Brandon wrote, “the kind of pure, unadulterated greed for which the Gilded Age was famous.”
The faith was never there. AI might turn on us someday or become racist, etc. https://spectrum.ieee.org/in-2016-microsofts-racist-chatbot-...
The faith is in nature from which human beings created the technology to solve things and make life easier. AIs are basically toasters that can solve problems, not like a human being that has feelings or even a soul. Remember the Sci Fi warnings of Cylons, Terminators, where the AI becomes a Frankenstein's Monster and turns on its creator.
