I tend to agree, but it depends on how something was tested. In “Darwinian Agriculture”, I argue that testing by ability to persist is weaker than testing by competition against alternatives. Trees compete against each other, but forests don’t. Societies often compete and their moral systems probably affect competitive success, but things are complicated by migration between societies, population growth (moral systems that work for bands of relatives may not work as well for modern nations), technological change (cooking pork), etc.

There are so many possible coincidences, it would be surprising if none of them happened.

I observed 2012 transit of Venus, right on schedule.

Don’t know an easy way to prove changing earth-moon distance, but changes in speed of earth’s rotation can be seen as changes in number of days per year, visible in growth layers in fossil coral. Taking a magnifying glass to the right museum might allow individual verification.

Great post!

Evolution of antibiotic resistance is indeed fairly easy, but how about evolving something visibly different? Evolution of simple multicellularity from a unicellular ancestor is easier than you might think: http://www.snowflakeyeastlab.com/

If we can solve the earth-orbits-the-sun problem, we don’t need to measure the parallax of stars accurately to show that they’re really far away, which seems like an important scientific truth.

Since most of these would, if successful, result in an imperfect copy of yourself, rather than extending your own consciousness, you could include “have children.” If you really want a perfect copy, rather than a genome enriched by a partner, then human cloning is closer to feasible than cryopreservation of adults. Cryopreservation of embryos actually works. I wonder if there would be a market for a service that promises to keep embryos frozen until life human expectancy reaches 110, say, then bring the embryo to life by whatever methods they are using then, sharing some of the trust fund with the foster parents.

Tax-deferred retirement accounts make sense if you expect your tax rate to be lower in retirement than now. I expect tax rates to increase, so would rather pay the tax now than when I take the money out. In US, Roth IRA allows that.

“Your Money or Your Life” is worth reading. Build up your savings and decrease your spending until earnings on savings equal spending. After that, you don’t have to work for money. Worthwhile work still enhances health and happiness, though.

Robert Frank’s books on economics make the point that relative income is more important than widely recognized. Two examples he may have missed: 1) it’s not just how much education you have, but how it compares to the competition. So the best-educated get the best jobs, but that doesn’t mean everyone would have a good job if everyone was better educated. 2) losing health insurance is a disaster if you are competing for health services with the insured. But if everyone loses health insurance (e.g., Medicare collapses), doctors will have to lower their fees.

You might like the “simple practice cases” in my recently published book, Darwinian Agriculture. Has natural selection favored solar tracking by leaves because it increases photosynthesis, or because it decreases the photosynthesis of competitors? What sex ratio (in reindeer, say) is favored by natural selection, and what sex ratio maximizes meat production from a given amount of lichen? Why do rhizobial bacteria provide their legume hosts with nitrogen, if healthier plants will indirectly help other rhizobia infecting the same plant—their most-likely competitors for the next host?

It’s even a little trickier than that. If overall population is increasing then one offspring this year may lead to greater proportional representation in the gene pool than two offspring next year. What few people recognize is that the opposite can be true if the population is decreasing.

But I think the original post assumed “all else being equal”, to allow focus on the main points.

I think that only works if you say “even if that were true, which we don’t need to discuss now, I would argue that...” It’s much harder to get someone to accept “for the sake of argument” something they strongly disagree with.

For example, I would only accept “morality comes from the Bible” if I had a convincing Bible quote to make my point.

You may find this story (a scientist dealing with evidence that conflicts with his religion) interesting.

In addition to the emotional issues you raise, there’s the question of thresholds and scalability. If the puppy program already exists, giving $10 will help more puppies. But, for many scientific research projects, there’s no point in even starting with less than $100K in hand. That could be $10 each from 10,000 people. An easy decision, perhaps, for the 9999th person, but who wants to give the first $10?

Elsewhere I’ve suggested “Social Escrow” as a solution. You pledge a certain amount, contingent on enough other people doing so and perhaps on other objective criteria. “Send us two checks. We’ll tear up both if not enough other people send checks. We’ll tear up the second if the research doesn’t meet kilometerstone X by date Y.”

Kickstarter has some of these features, but doesn’t seem to fund science.

I agree that some “limits” have proved illusory. But do you have an example where a limit based on conservation of matter or energy was surpassed?

I assume solar technology will continue to improve, but it would take several orders of magnitude of improvement for food-from-solar cells to be cost-competitive with cattle grazing low-value land. What does an acre of solar cells cost?

Yes, we should start with the low-hanging fruit. For example, nutrients in human waste are a small fraction of what’s in animal waste, and the latter should be easier to capture. Even so, much of the manure still gets applied at pollution-causing rates near barns and feedlots, rather than paying the cost of transport to where it is most needed.

But your point about food availability and social stability is more important. Recycling urine seems like a good idea. But a society that needs to recycle urine will be a society where many people are spending most of their income on food and others are going hungry, as was the case for the societies mentioned above.

Whatever past trends were, the rate of progress must slow as we approach physical limits. For example, there must be some minimum size for a reliable resistor. So even if we accept the inevitability of certain past trends, extrapolation is risky.

Once we’ve used most of the oil (or phosphate, for which there’s no substitute), past trends driven by culture, technology, or economics won’t continue. In agriculture, best-farmer yields haven’t increased much since 1980, although averages go up as they buy their neighbors’ land. (My recent book on Darwinian Agriculture discusses some prospects for improvement, but still within limits.) Cheap computer power may substitute for previous forms of education, entertainment, and travel, but not for food. I doubt that enough people will upload their brains to make a difference.

I agree with your main points, but it’s worth noting that corporations and governments don’t really have goals—people who control them have goals. Corporations are supposed to maximize shareholder value, but their actual behavior reflects the personal goals of executives, major shareholders, etc. See, for example, “Dividends and Expropriation” Am Econ Rev 91:54-78. So one key question is how to align the interests of those who actually control corporations and governments with those they are supposed to represent.

Would the first AI want more AI’s around? Wouldn’t it compete more with AI’s than with humans for resources? Or do you assume that humans, having made an AI smarter than an individual human, would work to network AI’s into something even smarter?

Either way, the scaling issue is interesting. I would expect the gain from networking AI’s to differ from the gain from networking humans, but I’m not sure which would work better. Differences among individual humans are a potential source of conflict, but can also make the whole greater than the sum of the parts. I wouldn’t expect complementarity among a bunch of identical AI’s. Generating useful differences would be an interesting problem.

That may be a faster route to AI. But my point was that making an AI that’s smarter than the combined intelligence of humans will be much harder (even for an AI that’s already fairly smart and well-endowed with resources) than making one that’s smarter than an individual human. That moves this risk even further into the future. I’m more worried about the many risks that are more imminent.

Does this have implications for the risks associated with AI? Tao is a lot smarter than we are, but he doesn’t seem to be plotting to harvest us for our phosphorus, or anything.

This example and others mentioned also suggest that interactions among intelligent agents may be at least as important as intelligence per se. If we can learn to work together more effectively, I think we’ll be able to out-think computers for a long time (where “a long time” is defined as long enough for over-population, climate change, nuclear war, etc. to be serious risks).

If you park near the St. Paul campus, there’s a free shuttle bus that stops across the street from Coffman. http://www1.umn.edu/pts/bus/connectors.html

I’m somewhat interested, but have plans already.

A “church-like organization that has local congregations and meets weekly to listen to talks on rationality, the latest scientific discoveries, lectures on philosophy, the state of the world, etc.”?

Sounds like a Unitarian fellowship, at least the ones I know. Some may be closer to their Protestant roots, though. Of course, they also have talks on irrationality (“spirituality”) and, while atheists and other rationalists are certainly welcome, aggressive promotion of any particular world-view is discouraged.

in reply to: CronoDAS’s comment on: Bayesians vs. Barbarians
I see how the first part of my post could be read as “we need to motivate girls to go to school”, which wasn’t my intent. More a matter of motivating tradition-bound parents to see educated girls as a major source of income. But I understand that going to school can be risky in Taliban-dominated areas, which is why the second part of my post was all home-based and therefore hard for the Taliban to detect. Even so, I agree that any obvious link to the US government could be a problem.
