More like the 1960s. For example, looking at old National Geographics and pop sci magazines you see an incredible optimism and respect for science, engineering, and the orgs that did them. All those "atomics of the future"-type stuff.

What changed was that the wall of secrecy broke down and stories of pollution, corruption, and all around bad behavior hit the public like a tsunami. Then we learned that governments had been lying to us over things like Vietnam, with the Pentagon Papers, Watergate etc. Pretty hard to be positive after that. The computerization of the 1970s through 1990s was broadly positively perceived until the 2000s when it became undeniable that Big Tech would do anything to harvest users. Cambridge Analytica. Cutting off Netscape's air supply. Embrace, extend, and extinguish. There are not many reasons to be optimistic.
