I too am frustrated by modern science fiction's need to be plausible. I want the weirdest shit an author can think of, that's how the sci fi I grew up with was, and that's how i like it. That's why my science fiction I write isn't plausible at all, and is just out there. I think this is personified by William Gibson writing real life novels now, and the same for like Bruce Sterling. Shouldn't these guys be using their imaginations to come up with far out stuff? Meanwhile Rudy Rucker is still writing the wackness though.
But yeah, that's one of my pet peeves too.
