Here is an excerpt from a longer post, which also includes a summary:
Here are some of the most interesting ideas in the book:
1. Mind speeds: I had not previously spent much time thinking about how our brain’s hardware affects the speed at which we think. As it happens, our minds are spectacularly slow compared to what’s feasible with other materials! Better hardware, as well inequalities of hardware across individuals, will likely drive many parts of em society.
2. Death in the time of copies: An individual’s relationship to death is much different when you can make and store copies of yourself. Given how much of our current lives and societies are wrapped in who dies / how they die / when we die – a world where death is less central has major implications for identity, values, and relationships.
3. Security concerns are paramount: Theft (making copies of you without your permission) thus becomes almost more of an issue than death. As such, laws and cultural taboos will shift with security becoming more central to em value systems.
4. Less democratic: In a short period of a time, a well run non-democratic regime can outperform your average democracy. However, in the modern human world, these regimes often implode on themselves before they can dominate the rest of the world. But in the em world, things will move so fast (economic doubling rates are incredibly fast, every month or two!), that the rewards to short bursts of effective non-democratic regimes may be very high.
5. Religion: I tend not to think of robots as religious, but Robin makes the case that the utility of religion (nicer hard-working people) and the values of the em world (more farmer like) should lead to increased religiosity.
6. Increased utility: The sheer number of ems, coupled with their high mind speeds – as well as the likelihood that there lives will be ok in terms of meaning and happiness – suggests that the transition to an em world will be a positive utility move.
