If we spent the last thirty years inspired by what we saw in Star Trek, what’s going to inspire us for the next thirty? If Hollywood’s fixated on the now, then the only futurism we have is funded by Silicon Valley venture capitalists and massive tech companies.
Actually, I cast my net even wider, and demanded that SF not simply be content with showing us the gadgetry of the future. Anyone can do that now, and they're not even obliged to do it particularly well for it to be salable.
What's far harder is to imagine the human being of the future. All these "futuristic" toys tell me nothing about the kinds of human beings that would be wielding them — or, rather, it tells me that the human beings using them would be even duller and more materialistic than the ones we have now. That's not a future I want.
SF is always a product of its moment in time, but that should be a constraint to be pushed against and transcended, not capitulated to. But when you have technocrats like J.J. Abrams in charge, people who are hired not to be imaginative and visionary but to simply use their skills to maximize the profitability of a franchise, I'm not sure anything else is possible.
