Conclusion

1. According to SM, the whole world is a kind of a social construct. All natural, social and metaphysical entities are designed, instantiated, and maintained collectively by all people via the ISO machinery.
2. The ISO machinery implies existence of the logically-cohesive stories (hypotheses, theories, models, propositions) in the realm of abstract forms. Some of these stories are instantiated via human practices. The process of the instantiation creates new particulars extending the established body of the empirical knowledge (ie knowledge derived via observation). Conversely, when the empirical knowledge is lost, the corresponding particulars disintegrate into the state of abstract entities (superposition of hypothetical states).
3. SM is plausible – the power of arguments underpinning this theory, I think, is compatible to the strength of arguments of many other storied-worlds.
4. SM is not exclusive - there are other epistemologically plausible descriptions of the world. For an individual to internalise one of such descriptions, non-epistemological factors will play a critical role (e.g. upbringing, culture, media, education, idiosyncratic preferences etcetera).

Take home points

1. When it comes to fundamental questions concerning the human nature and the functioning of the universe, many people are caught up in the web of stereotypes and never bother questioning these stereotypes - they don’t scratch them hard enough to see there is nothing fundamental beneath. Furthermore, some people just don’t care to know who they are and where they live. According to SM, our current believes and practices define our past, present, and future lives, including our afterlife. We die as we live. Don’t risk it - take care of yourself.
2. According to SM, there is no such thing as the only real world. Instead, there are many different all equally real worlds. People can migrate from one world to another or even create their own worlds tailored to their own needs. Beware, however, of the dangers accompanying the exploration of the new worlds – however meticulous design, you never know exactly what you will run into. If in doubt, don’t risk it – stick with the established storied-world proved by time.
3. Multiverse travellers must have immunity against the existential void via the development of a prior sustainable well-being.
