Computronium and hedonium

Computronium is sometimes defined as an arrangement of matter that is the best possible form of computing device for that amount of matter.

Many futurists have become enamoured of the idea that a future cyberspace will consist of computronium.

The idea that far future creatures will turn matter into computronium seems to be largely based on projecting out the trend towards larger brains. However, there is another relevant aspect - we know from scaling laws is that larger greatures have relatively smaller nervous systems, and relatively larger muscular, skeletal and digestive systems. The organism with the highest brain to body ratio is an ant.

Some hedonists have a similar concept: "hedonium". That represents the arrangement that represents the highest state of pleasure for a given amount of matter.

After giving appropriate weight to the metabolic scaling aspect, I think that "computronium" or "hedonium" are probably not much like what most matter will turn into in the future. The idea ignores biological optimization targets. The purpose of most living things is not to compute or to represent pleasure - but rather to survive and reproduce. It is a different optimization target. Structural, digestive and metabolic elements are especially true if resources are limited and there is competition for them. That is the state which most living ecosystems gravitate towards. It results in more of a zero-sum environment, where to obtain resources to have to deprive another agent of them.

I think that futurists have been fetishizing intelligence and computation. As an example, consider Moravec's "Pigs in cyberspace" article. Planty of references to computation, but muscles and metabolism are sidelined. Bodies themselves are considered expendable and ephemeral. To me, it seems like a weird and twisted perspective which poorly reflects what we know about living systems. It's not that there won't be a cyberspace, but rather than it is likely to be be the tip of an iceberg consisting of other metabolic processes.

Meme warfare dynamics

Meme warfare is mediated by small, fast-moving particles - photons and electrons. Gene warfare is slower and typically involves more protons and neutrons. Memes are able to spread over considerable distances at near light speed, and can penetrate further and faster, but the dynamics are are a bit different from gene warfare. Recipients can choose to put their fingers in their ears and ignore the alien propaganda - if they so choose. So: it needs to be palatable fare - laced with gifts and treasures. However if the meme invasion is to be followed by a "gene" invasion involving real matter, it should not provide the enemy with too much useful technology. This is likely a common situation.

There have been a few SF stories about meme invasions leading directly to gene invasions without the use of spaceships or other classical invasion tools. Fred Hoyle's A for Andromeda is a classic example. It is an interesting possibility. There might be a window of opportunity between a civilization being born and its memetic immune system maturing - during which it could be more vulnerable to such attacks. Maybe technological gifts can be interwoven with alien propaganda in a manner that enticies the recipient to digest the message - even if it contains elements that conflict with their developmental process. I wrote about this possibility here before - back in 2013.

Another consideration here is how the economics of long-distance meme warfare work. Organisms typically face a tradeoff between local growth and development and large-scale distribution of pollen or seeds. When it comes to civilization using its local resources to send out messages through interstellar space a complex cost-benefit analysis is involved to see whether it is likely to pay off. It seems likely to be advantageous to identity living systems and then broadcast to them directly using lasers. Perhaps this is part of the reason why some stars seem to twinkle.
