Soon! We just need an API to hook DF into a raspberry pi and the raspberry pi to provide some mutually meaningful gameworld feedback, and we're in business. We could have dwarf-powered robots in no time.
Now, they might not tantrum over finding out about the real world. But they could be made to.
Though...
If you program something to feel pain, if you tell it to act like it does and move towards stopping it, if other programmed things around it react to the pain in a way that's relevant, you've caused it pain. Oh, sure, it's not like our pain. Our pain was evolved, is based on chemicals instead of electrons, represented by our reactions in the real world instead of one with dragons. But the distinction is entirely arbitrary.
In that sense, every time you've killed a video game character could be considered a violation of their basic sense of self-preservation. DF takes it much farther than other games - most game AI won't run away, or form friendships, or grieve for their loved ones. Maybe this is overanalyzing, and they haven't passed some threshold of true feelinglikeness, where they don't quite do all the things we need to do because they didn't have all the little pressures we've had over the past few millions of years. Maybe that makes it ok. Or maybe we'll look back on this time as an age of unknown and uncountable tragedy, a brief madness before true contact with our own homegrown brand of alien was truly initiated on equal terms.
Good night.
