Must Watch: Bill Nye, Neil deGrasse Tyson, Pamela Gay, and Lawrence Krauss discuss our future in space. Just need to rebut that very last point Mr Tyson made before the video ended.
Yes, deflecting asteroids probably takes less energy and effort than traveling to another solar system, or terraforming mars. However, those methods of colonization are not the logical first step to take. The logical first step towards colonizing other worlds and other solar systems, is to build orbital colonies. Massive ring shaped structures that can house millions of people each. To be certain we aren't anywhere close to that now, but the technology to divert asteroids gets you most of the way there.
Additionally, you kinda have to take this route eventually. And before anybody says it. Monkeys 'feel' texture of virtual objects - life - 05 October 2011. Video: Monkey brainwaves control avatar Monkeys have feelings too.
In a mind-meld between monkey and computer, rhesus macaques have learned to "feel" the texture of virtual objects without physically touching a thing. In the future, prosthetic limbs modelled on similar technology could return a sense of touch to people with amputations. Using two-way communication between brain and machine, the monkeys manoeuvred a cursor with their minds and identified virtual objects by texture, based on electrical feedback from the computer. Miguel Nicolelis of Duke University Medical Center in Durham, North Carolina, and his colleagues implanted electrodes into the brains of two monkeys. The team then assigned a unique texture to each of three identical circles on the screen.
Random circles When the circles were randomly moved on the screen, the monkeys were able to identify the circle associated with the reward with around 90 per cent accuracy.

Scientists have recorded the first experimental evidence that elephants experience "eureka!" moments. Did you read the article?
Yes, and it's that description that makes it seem like trial and error. If this were indeed trial and error, the elephant would of repeated those steps more times until he got the branch. I think what you're seeing above is the elephant going through different scenarios, taking a break, then coming back with a better idea of how to achieve his goal. Similar to playing a video game and trying to beat a level. Frustration builds up and you spend all day trying to beat said level to no avail. Tl;dr: the elephant is actually smart. "He moved the cube in two of the first six sessions (sessions 1 & 4), but never towards the food. " "Four minutes into the session, he obtained the fruit but was unable to pull down the entire branch. Sounds like he got it the first time he used the cube in that manner...
