To What Extent are Humans Optimized?

To what extent are humans optimized? Compared to the most efficient method of land mobility (that still retains all the same functionality e.g. ability to climb stairs) how efficient are human legs? Compared to the most efficient way to take in their respective types of data, how efficient are human eyes, ears, etc?

Most importantly, compared to the most efficient way to do the types of calculations it does, how efficient are human brains/neurons etc.? Obviously, digital computers are much more efficient at the types of computations they do. With semiconductors as an obvious counterexample, we can be fairly certain that any digital computation human brains do is not even close to the theoretical maximum efficiency it could have. But I've heard some say that human brains might use certain types of analog computation at least in part. Is it possible that the analog parts of human brains are even e.g. 10 percent as efficient as a maximally efficient version of computational substrate designed for a similar purpose?

Obviously, all the answers to this will probably be well within the realm of conjecture. Unless, that is, anyone actually does have some sort of publication going into detail about this type of thing, but I doubt it. I'd still like to see what this community cares to predict about this subject/offer as conjecture.

The left recurrent laryngeal nerve and the vas deferens are classic examples of suboptimal anatomical features. One might imagine there are structures in the brain that are suboptimal in a way that is analogous to the left recurrent laryngeal nerve and the vas deferens. Perhaps there are some we have yet to recognize as such because we don't understand how the brain works.

minimizing how many instructions you need to add to the genome in order to make something happen

This is the mechanism for why the body isn't fully optimized: it has to be backwards compatible and build iteratively off of previous DNA. That tech debt is exactly what an artificial engineered brain/body could re-design.

That makes sense, direct editing is going to cause a lot of indirect problems. Similar to immune system or dietary supplements.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
