Re: science fiction / thought experiments, I recently read some of Asimov's writing; it gets kinda tedious to be honest, a lot of his sci-fi (or at least the bits I read so far) is taking his Three Laws and experimenting on how those can be interpreted and executed, results often ranging from inaction (conflicting rules) or extreme action (lock up the humans to conform to rule #1) (see the plot of the I, Robot movie (which btw has little to do with the book)).
