The Future of Life Institute has published their document Research priorities for robust and beneficial artificial intelligence and written an open letter for people to sign indicating their support.
Success in the quest for artificial intelligence has the potential to bring unprecedented benefits to humanity, and it is therefore worthwhile to research how to maximize these benefits while avoiding potential pitfalls. This document gives numerous examples (which should by no means be construed as an exhaustive list) of such worthwhile research aimed at ensuring that AI remains robust and beneficial.
After the first few pages of signatories, I recognize very few of the names, so my guess is that LW signers will just get drowned in the much larger population of people who support the basic content of the research priorities document, which means there's not much downside to lots of LWers signing the open letter.
