You're going to have a hard time pointing to utopian novels from the same period. It's not that something closer to utopia was never possible. A lot of CS from the 70s was explicitly utopian. Even the Jobs "bicycle for the mind" idea was far more utopian than "Let's create a monopolistic monoculture with adtech and noise." For some reason the cyberpunk writers chose not to imagine it or promote it. Warp drive is similar. It seeded the idea of FTL in the popular consciousness and made it something almost everyone has heard of. Without that, it might have remained an abstract curiosity. In Propaganda, Bernays says that instead of preaching at the public you need to dramatise the behaviours and beliefs you want to see the public adopt. The ad industry is based on this, but of course it runs through fiction and other media too. Star Trek is one of the few attempts to dramatise a utopian future. Everything else is a wasteland of darkness. And it has certainly had an effect.
