Audiobook version is "in the works", coming "probably in a few months": https://youtu.be/KOHO_MKUjhg?feature=shared&t=2997

Is there any crucial consideration I’m missing? For instance, are there reasons to think agents/civilizations that care about suffering might – in fact – be selected for and be among the grabbiest?

David Deutsch makes the argument that long-term success in knowledge-creation requires commitment to values like tolerance, respect for the truth, rationality and optimism. The idea is that if you do not have such values you end up with a fixed society, with dogmatic ideas and institutions that are not open to criticism, error-correction and improvement. Errors will inevitably accumulate and you will fail to create the knowledge necessary to achieve your goals.

On this view, grabby aliens need values that permit sustained knowledge growth to meet the challenges of successful long-term expansion. An error-correcting society would make moral as well as scientific progress, and so would either value reducing suffering or have a good moral explanation as to why reducing suffering isn't optimal.

This is somewhat like a variation of the Instrumental Convergence Thesis, whereby agents will tend to converge on various Enlightenment values because they are instrumental in knowledge creation, and knowledge-growth is necessary for successfully reaching many final goals. 

Here are two relevant quotations about alien values from a talk David Deutsch gave on optimism

the only moral values that permit sustained progress are the objective values of an open society and more broadly of the Enlightenment. No doubt the ET’s morality would not be the same as ours, but nor will it be the same as the 16th century conquistadors. It will be better than ours.


the Borg way of life... doesn’t create any knowledge. It continues to exist by assimilating existing knowledge. … A fixed way of life. … it is never going win in the long run against an exponentially improving way of life 


Looking forward to reading the book. I hope there’ll be an audiobook available in the UK too!

Thanks for sharing this, I just finished the audiobook and really enjoyed it. I recommend it: it’s engagingly written and gives an interesting insight into Parfit’s powers and peculiarities. I enjoyed getting some context about the beginnings of EA as well.

Should we be maximising expected value across many-worlds?

Assume the many-worlds interpretation of quantum mechanics is true.

Rather than pursuing  high-upside, low-probability  moonshots, which fail more often than they succeed, might it not be more effective to go for interventions that robustly generate value across as many worlds as possible? 

The human alignment problem

Humans are subject to instrumental convergence  as much as  an AI would be. We seek power, resources and influence in pursuit of many of our goals.

Whatever our goals happen to be, we will want to use AI to help us increase our power to help us get what we value.

If people are augmenting their goal-seeking with AI, will we converge on harmonious goals, or will we continue to pursue parochial self-interest?

In short, if we somehow solve the alignment problem for AI, will we also solve the human alignment problem? Or will we simply race to use AI to maximise our own power and our own values, even if these harm others? 

The best hope is that if we solve AI alignment, the AI will keep us in check in a benevolent and minimally impactful way. It will prevent us from pursuing zero-sum goals and guide us to be better versions of ourselves. 

But this kind of control may well appear misaligned from our current perspectives, in that some people's  cherished goals and values may not be the ones the AI chooses to support. 

So to talk of aligned AI is to gloss over the possibility that it is likely to be misaligned with a great many peoples’ current goals and ambitions.

You might consider creating a text-to-speech version by using e.g. Amazon Polly. Whilst imperfect, it is listenable and might be useful to people. Here is a sample generated with the British English Arthur Male voice.

A key point about Ben Franklin is that his longtermist efforts were for the benefit of the future, whereas EA-style longtermist causes like AI risk and biosecurity are about ensuring there actually is a future. 

I think as long as there are x-risks that we can plausibly influence there will be people carrying the torch for longtermism in one form or another. 

  1. Imagine someone who believes that eating meat is morally wrong, but who nevertheless eats meat and 'offsets' their meat-eating through donations to effective animal charities.
  2. Imagine someone who believes slavery is morally wrong, but who nevertheless owns slaves and 'offsets' their slave-owning through donations to the abolitionist movement.

An  argument for 1 goes: "The impact of me not eating meat is negligible. The personal cost to me of not eating meat is appreciable. Time, money and effort spent following  a restrictive diet may limit my effectiveness to do good elsewhere. My donation is the optimal path to reducing animal suffering".

And an argument for 2 goes: "My slave-owning is very modest, and is a drop in the ocean in the big picture. I can effectively use the economic surplus generated by my slaves to end slavery sooner. If I free my slaves I'll be poorer and will have less money to donate, and so I'd do less good overall."

Whilst the situations are not symmetric, they are similar enough that I feel like I want to say "If you care about animals, you should support animal charities AND go vegan" in the same way I want to say "If you care about slaves, you should support abolition AND free your slaves".
