Some of this I agree with. While many technological advances have come our way there are still many authors writing about topics that don't just involve high tech gadgets. Philip K Dick wrote the ideas for "The Minority Report" in 1956... those ideas to this day are still impossible and out of reach. Dan Simmons 4 book Hyperion series is an amazing work of Science Fiction that is no less amazing now than when it was published.
The ideas are there, unfortunately I feel the fan base isnt, or at least the fan base that watches more TV than reads books (which is the REAL target audience for syfy).
