Save Humanity! Breed Sapient Octopuses!

I searched some more. In 2013, scientists selected for brain size on guppies and got 9% larger brain in 2 generations. Guppies with larger brains were smarter. This seems to validate feasibility of breeding program and suggests a simple method to select for intelligence.

I know this was tagged as humor, but taking it seriously anyway,

I'm skeptical that breeding octopuses for intelligence would yield much in the way of valuable insights for AI safety, since octopuses and humans have so much in common that AGI wouldn't. That said, it's hard to rule out that uplifting another species could reveal some valuable unknown unknowns about general intelligence, so I unironically think this is a good reason to try it.

Another, more likely to pay off, benefit to doing this would be as a testbed for genetically engineering humans for higher intelligence (which also might have benefits for AI safety under long-timelines assumptions). I also think it would just be really cool from a scientific perspective.

Why not breed for compatibility with human values as well? We could then study the differences between various degrees of "aligned" cephalopods and wild cephalopods.

It might be easier than selecting for intelligence too; humanity has successfully modified dogs, cats, and livestock to provide more positive utility to humans than their wild counterparts, but hasn't drastically increased the intelligence of any wild animal to my knowledge, despite there plausibly being benefits for doing so with ex. horses or dogs.

Breeding for human values also limits some of the downsides of this plan, like the chance of ending up conquered by unaligned octopuses.

Sorry, had to be done!

I think the risk of unaligned octopuses taking over the world is lower than the risk of unaligned AGI:

• We know how to stop breeding octopuses once they reach human intelligence.
• Even once octopuses reach human intelligence it might take a long time for them to learn the technology required to win a war against us.
• They have short life spans, so limited time to learn new technologies or cultural evolution. The idea would be to see how long it took for octopuses to solve the sort of problems uneducated intelligent people could, not invent novel mathematics.

Planet of the Squids!

Judging by the fox domestication experiment, intelligence could emerge way sooner than 50 generations. The fox experiment used a population size on the order of 1e2, and selected the top 20% most docile foxes to act as the breeding pool for the next generation. You could accelerate this process by increasing the population size, while selecting a smaller fraction of intelligent octopuses.

Sounds like a good idea!

Why this specific species? Introducing a new model organism is a large investment. After a brief search, I actually found a proposal to introduce octopus as a new model organism, but choosing a different species.

The Lesser Pacific Striped Octopus, Octopus chierchiae: An Emerging Laboratory Model (2021)

Some choice quotes:

Despite the immense potential for comparative biological research between octopuses and vertebrates and aquaculture advances from the husbandry of other cephalopod species, a sustainable, multigenerational laboratory octopus model has yet to be attained. [cites researches starting from 1977] (snip) Here, we overcome these challenges by advancing the laboratory aquaculture of the lesser Pacific striped octopus, Octopus chierchiae.

So the necessary basic work is now done. Maybe culturing other octopus is now easier based on this success, but I won't bet on it, given that it failed for >40 years. On the other hand, I must admit it doesn't seem much effort was spent on this problem in those 40 years.

Didn't learn this until recently but it seems that the plural of octopus is octopi
