I would agree that "GMO" is too broad a label -- but if anything, this is an argument for more labeling, rather than less.

Let's look at established food technology. It would not be helpful to simply list "WARNING: Contains synthetic ingredients" on packaging. Nevertheless, this does not stop us from requiring producers to clearly label what is in the food, in the form of an ingredients list. We do this despite the possible "public confusion" that could be caused by the fact that most people do not know what, e.g., "sodium benzoate" is.

If we are now putting other new ingredients in our food -- at the genetic level -- then it would seem that these changes should also simply be listed, with a little more specificity than, "WARNING: GMO," in the ingredients list. E.g., don't just list "corn;" list "corn (Monsanto RoundupReady (TM) strain 2.09387)."

There is also a suspicion now that sublethal effects of glyphosate (Roundup) are making bee colonies susceptible to infection by other pathogens, and that this "one-two punch" is what's causing colony collapse. I wouldn't want to risk something essential -- pollinators -- just to get marginal boosts to yield.

Wait, did they [write well]? Do you have metrics to show it?

I can't generalize, but I believe that my own writing was better in high school and early college than it is now. Whenever I stumble across one of my old essays I am amazed.

After nine years of engineering school, those skills rust over.

I am also frequently amazed by books from a generation or two ago. Compared to the stream of articles I typically read, they're a breath of fresh air.

On the other hand, when I pick up old video games that I remember being hard, I beat them easily, even though I haven't touched them -- for whatever that's worth.

My understanding is that a need for gold (to use as currency) was a major reason for the Roman invasions first of Gaul (recent finds show pre-Roman Celts had significant gold-mining operations) and then of Dacia (now Romania). We can say with more certainty that gold was a major motive of the Spanish conquest of the New World.

The mechanism by which commodity-backed currencies motivate wars looks pretty straightforward: If your economy grinds to a screeching halt and you want to do "quantitative easing," you need to physically go out and grab more of the commodity. Fiat currencies avoid at least this issue -- and your argument about them being useful for funding wars seems to apply just as well to funding any other activity.

(It's also worth noting that, if you do have a gold or a gold-backed currency, and you do succeed in grabbing a bunch of coin from your neighbors, then, despite being commodity-backed, you will still have inflation. Apparently this is what happened in the Spanish empire as a result of all that New World gold.)

I just ran these numbers to see what they would say. I assumed the upper bound would be absurdly high. If I have not made a mistake, the bound is actually disturbingly close:

A bit of googling tells me that, in a year, the sun puts out 150 EJ.

It is said that people should consume 2000 kCal/day = 3.05 GJ

To get an upper bound on the number of people that can be supported, we take the ratio, to get 4.92e10.

The current world population is 7e9. This is 1/7-th the upper bound.

The doubling time for the world's population, at current growth rates, is (after some more googling), 54 years. That means that it will increase by a factor of 8 -- more than can be supported -- in just 162 years. More precisely, it will increase by a factor of 7 in 152 years.

That's about two human lifetimes.

Either (1) my numbers are wrong, (2) I made an arithmetic mistake, (3) growth will level off very soon, (4) we will learn to practice space agricuture at a massive scale in an implausibly-short timeframe, or (5) we're in for some pain.

A number of northern European countries -- Sweden, Denmark, Norway, Finland -- provide state health care and pensions, but also respect individual liberties to an extent sometimes even beyond in the United States.

Denmark is #3 in the World Audit Civil Liberties rankings.
Finland is #1
Sweden is #2
Norway is #5
The United States is #15.

These are the classic "Third Way" democracies -- and they outnumber the Stalinist states (USSR, North Korea, Cuba) that are always put up as straw men. In short: Your argument sounds compelling, but, like Aristotle's reasonable-sounding assertion that heaver objects accelerate faster in freefall, it is not supported by empiricism.

If I'm not mistaken, your basic iPhone has most of this built in. It's aware of its orientation and location, and it has a camera. Speed could be dealt with in a variety of simple ways, and avoidance problems minimized.

One of my labmates did exactly this, on Android, for a project involving (IIRC) the Air Force (He flew the resulting drone at a nearby airbase, at least). The thing worked; he controlled it by sending text messages.

It makes more sense to put more people on smaller land (do away with yards altogether) for energy efficiency/cost reasons than to have millions of sub-acre semiproductive farms.

Along the same lines: Why give 100 people each tiny yards, when they can have nice apartments next to a large park instead? I think the New Urbanists have it right.

I don't know, or care, whether atheism "is a religion." In fact, I don't even know what that sentence means.

What I do know is that, like the religions, it is becoming a group identity -- an "-ism" -- as evidenced by the extremely defensive posts being made here. If it were just a collection of ideas relating to abstractions, if people didn't identify with those ideas, if people didn't see attacks on those ideas as attacks on themselves, then nobody would care enough to get angry.

Maybe that's ok. Maybe it's useful. Maybe, most atheists grew up in staunchly religious communities, and the politics of group identity, of belonging to an oppressed minority, are helpful to resist a more generally destructive culture of religious bigotry.

But for those of us who were lucky enough to grow up in a secular environment, it gets annoying. Me? I don't need to "fight back." I'm not so afraid of the concept of God that I need to destroy it. It's an abstraction. Asking whether it exists is meaningless. Do the integers exist? Mu. I like Spinoza. I'm cool with panpsychism (what makes your unfalsifiable worldview better than mine? Maybe contemplating my part in Infinity alters my outlook.). We can flirt with ideas without marrying them. Unitarian Universalists? Sometimes too New-Agey for my tastes (For me, "energy" is measured in Joules), but I think the basic idea is the right one. Jesus of Nazareth? He did say things worth hearing. The Beatitudes? The Golden Rule? I don't need to accept Old-Testament jingoism, or Paul's sexual issues, or the dogma of a politicized medieval Church, or the divinity of Christ, to recognize that they stand on their own merits (and probably predate Jesus, which is OK).

The other day, I saw a car, with two bumper stickers. One was the common "CoEXiSt" sticker. The other was a shot at Christians. They're at odds, no? Get along, I say.

If you consider that there is a modest practical limit imposed on the number of units that can fire on one another at a given time, isn't there an inherent advantage for the army that's twice as effective that engages the army that is half as effective but twice as large?

Yeah... It seems reasonable to guess that the effective power of an army grows quadratically for small numbers of units, but more-or-less linearly after that -- and terrain advantages like chokepoints can shift when that transition between quadratic and linear growth happens (E.g., if three units can get through a chokepoint at a time, then the transition probably happens around three).

I suppose that if you really want an answer, you need to do some experiments, and compile some statistics! Custom maps seem like a good way do this... I'd be surprised if hardcore Starcraft players hadn't already done these kinds of studies...

Ok, let's see... In your model, a group of n units has fighting power proportional to n*sqrt(n). Good! As expected, it's slower-than-quadratic, but faster-than-linear. Sounds like what I read people measure empirically.

Specifically, say

dx/dt = -a y^q

dy/dt = -b x^q

for some a,b,q>0; for you, q=1/2. Then the quantity

D = a y^(q+1) - b x^(q+1)

is conserved.

More generally, if

dx/dt = -f(y)

dy/dt = -g(x)

then, letting F and G be antiderivatives of f and g respectively, the quantity

D = G(x) - F(y)

is conserved.
