No.19999
Regardless of whether or not a "belief in God" remains a majority opinion, the religious sense will still prevail. I think religion, in the traditional sense, will remain for some time. People that are marginalized, will turn to it, as will people who are prosperous. However, if you look at religion as an aspect of the zeitgeist, I think that, although its fundamental views and tenets have dramatically shifted, its overarching, unifying function persists. To look at a culture's religion, one must look at the core beliefs held by a society. In the current case, the underlying, unifying principle is the technological. Devout members of all major religions, as well as the non-religious, embrace the technological. The technological has transfused and transubstantiated all major religions. Even radical groups that oppose it grapple with it, and, according to the Nietzschean mantra, they will become the monster they are fighting.
One shouldn't underestimate the significance of the technological in modern religious belief. In fact, such a belief is paramount to our contemporary belief system. To see this, at least in first world countries, just look at spending habits. The tacit assumption that underpins most people's lives, even people of conflicting religious views, is that technology tends to, ultimately, resolve problems (which is contrary, at the very least, to the cyberpunk view, (incidentally, it is also contrary to the ancient Christian view. In fact, since the scientific revolution, the church has increasingly donned the skeptical, progressive, evolutionary, in short the technological, belief system of science)). A good example of the religious instinct being grafted onto the technological can be found in E.M. Forster's story "The Machine Stops".
Ultimately, regardless of whether or not most people answer yes to "Do you believe in a higher power?" (and I believe most will answer yes for quite some time), such a belief will persist, in some form (increasingly tied to the technological) and that will be the unifying, guiding principle of whatever shape civilization has taken.
