Two thoughts from Rudy Rucker:
"All living things are gnarly, in that they inevitably do things that are much more complex than one might have expected."
"One of the nice things about science fiction is that it lets us carry out thought experiments."
that IS a nice thing about science fiction.
before sci-fi existed, people must have just been sitting around thinking "i wonder if there's a way that we might be able to carry out thought experiments in the future. oh well! no use experimenting with THESE thoughts. back to writing non-fiction and non-science-fiction only!"
thanks for sharing!
