 The last decades have witnessed an increase in ethical inquiries into specific technologies. This may now be the largest of the three strands discussed, especially given the rapid growth in technology-specific ethical inquiries in the last two decades. One of the most visible new fields is probably computer ethics (e.g., Moor 1985; Floridi 2010; Johnson 2009; Weckert 2007; van den Hoven &amp; Weckert 2008), with more recently a focus on robotics, artificial intelligence, machine ethics, and the ethics of algorithms (Lin, Abney, &amp; Jenkins 2017; Nucci &amp; Santoni de Sio 2016; Mittelstadt et al. 2016; Bostrom &amp; Yudkowsky 2014; Wallach &amp; Allen 2009). But biotechnology has spurred dedicated ethical investigations as well (e.g., Sherlock &amp; Morrey 2002; P. Thompson 2007). More traditional fields like architecture and urban planning have also attracted specific ethical attention (Fox 2000). More recently, nanotechnology and so-called converging technologies have led to the establishment of what is called nanoethics (Allhoff et al. 2007). Other examples are the ethics of nuclear deterrence (Finnis et al. 1988), nuclear energy (Taebi &amp; Roeser 2015) and geoengineering (C. Preston 2016).
