US army’s report visualises augmented soldiers & killer robots.


The US Army’s recent report “Visualizing the Tactical Ground Battlefield in the Year 2050” describes a number of future war scenarios that raise vexing ethical dilemmas. Among the many tactical developments envisioned by the authors, a group of experts brought together by the US Army Research laboratory, three stand out as both plausible and fraught with moral challenges: augmented humans, directed-energy weapons, and autonomous killer robots. The first two technologies affect humans directly, and therefore present both military and medical ethical challenges. The third development, robots, would replace humans, and thus poses hard questions about implementing the law of war without any attending sense of justice.

Augmented humans. Drugs, brain-machine interfaces, neural prostheses, and genetic engineering are all technologies that may be used in the next few decades to enhance the fighting capability of soldiers, keep them alert, help them survive longer on less food, alleviate pain, and sharpen and strengthen their cognitive and physical capabilities. All raise serious ethical and bioethical difficulties.

Drugs and prosthetics are medical interventions. Their purpose is to save lives, alleviate suffering, or improve quality of life. When used for enhancement, however, they are no longer therapeutic. Soldiers designated for enhancement would not be sick. Rather, commanders would seek to improve a soldier’s war-fighting capabilities while reducing risk to life and limb. This raises several related questions.

Scientists have sequenced the entire genome of the tardigrade, AKA the water bear, for the first time. And it turns out that this weird little creature has the most foreign genes of any animal studied so far – or to put it another way, roughly one-sixth of the tardigrade’s genome was stolen from other species. We have to admit, we’re kinda not surprised.

A little background here for those who aren’t familiar with the strangeness that is the tardigrade – the microscopic water creature grows to just over 1 mm on average, and is the only animal that can survive in the harsh environment of space. It can also withstand temperatures from just above absolute zero to well above the boiling point of water, can cope with ridiculous amounts of pressure and radiation, and can live for more than 10 years without food or water. Basically, it’s nearly impossible to kill, and now scientists have shown that its DNA is just as bizarre as it is.

So what’s foreign DNA and why does it matter that tardigrades have so much of it? The term refers to genes that have come from another organism via a process known as horizontal gene transfer, as opposed to being passed down through traditional reproduction.

By 2030 solar energy will have the capacity to meet all of our energy needs. The production of food and clean water will also be revolutionized.

If we could capture one part in ten thousand of the sunlight that falls on the Earth we could meet 100% of our energy needs, using this renewable and environmentally friendly source.

As we apply new molecular scale technologies to solar panels, the cost per watt is coming down rapidly. Already Deutsche Bank, in a recent report, wrote “The cost of unsubsidized solar power is about the same as the cost of electricity from the grid in India and Italy. By 2014 even more countries will achieve solar ‘grid parity.’”

The total number of watts of electricity produced by solar energy is growing exponentially, doubling every two years. It is now less than seven doublings from 100%.

Similar approaches will address other resource needs. Once we have inexpensive energy we can readily and inexpensively convert the vast amount of dirty and salinated water we have on the planet to usable water.

Each year, an estimated 70 million sharks are killed for their fins. The brutal shark finning process involves cutting off a live shark’s fins and returning the debilitated animal back into the water to die a slow death. Highly valued in traditional Asian medicine and cuisine, the fins can sell for as much as $300 a pound on the black market.

What if an artificial shark fin could remove sharks from the equation completely?

New Wave Foods, a San Francisco-based sustainable seafood company, is developing a bioengineered fin product that could pull the rug out from underneath the shark trade.
