Hello mister Stallman, I really appreciate the rules that you have set up for free software, notably by the GPL, that enable us to enjoy the use of non-proprietary software everyday. My question is about what I think is an emerging new dimension in software power, impact on society, and licencing. Concerning the recent acquisition of the very secretive artificial intelligence company Deepmind by Google, I read that DeepMind required that Google create a joint Google / DeepMind ethics board as a condition of the deal, which would create rules for what Google could do with the technology. It seems to me that most artificial intelligence software today (Siri, Cyc, Watson, DeepMind, ...) are proprietary software, even if they massively use free resources like Wikipedia. Do you feel concerned by the ethics of possible artificial intelligence software usage? Given the possible dangers of this kind of software (see Kurzweil's Singularity) and the fear it inspires to most people (see most of the science fiction literature - except Asimov), do you feel the need for a new kind of licencing for this kind of software? (Sorry for my mistakes in English, I'm not a native speaker)
