Here we list a few examples of possible types of self-improvements (Section 6.1), Gödel machine applicability to various tasks defined by various utility functions and environments (Section 6.2), probabilistic hardware (Section 6.3), and relations to previous work (Section 6.4). We also briefly discuss self-reference and consciousness (Section 6.6), and provide a list of answers to frequently asked questions (Section 6.7).
