Cybernetics and Transhumanism: A New Hope


Prosthesis - I can see nothing wrong with it. It's giving back what we once had or should have had. For those who are disabled, and have missing limbs, I believe this would be especially important as it gives those disabled the abilities they should have had. It is nice that dreams won't be shattered due to prosthesis, we have the famous Oscar Pistorius. Despite him having had both his legs amputated from the early ages of 11 months, he was still able to run in the 400k/m race at the 2012 Paralympics and even the 2012 Olympics against fully able contestants.

On a different spectrum of Transhumanism, I also read an article recently on LiveScience.com (2013) on how a drug used to treat type-2 diabetes also has the ability increased the life expectancy of mice. The mice which were fed this drug lived an extra 5% longer than normal. These mice were also known to be more physically fit at an old age. Mice however which did have an increased amount of this drug, died earlier than normal due to kidney failure.

These types of findings could, of course, one day spread to humans. A lot of people would dream to see their great grand children, or reach another century. Although with that being said, it would not be a good thing if humans were to live much longer than we do now, otherwise earth would become over populated - but an extra 5% would not seem that bad!

There are many sci-fi programmes and films that go through a bunch of these Cybernetics and Transhumanism functions which currently do not exist or are in working progress. A sci-fi film of which I find very fascinating is Neil Burger's Limitless, which includes the made up drug NZT. "You know how they say we can only access 20% of our brain? This lets us access all of it!" (Limitless, 2011).

Something of which sounds rather nice on the surface, but could get a little out of hand if it had actually existed. "Even if everyone had an IQ of 200, you'd have exactly the same range of personalities as you have now, and because that's a determining factor in how good your society is, you won't necessarily have a better society" (Richard Haier, a neuroscientist and professor emeritus at the University of California, 2013).

But what about genetically modifying babies before their born, we have the capabilities of changing their hair, eyes, metabolism, IQ (Buzzle, 2012). Personally, this is not something I would want to do, editing the features of your child, in my opinion, make it so that the baby is no longer yours.

Algorithms: Attack of the Predictions

Algorithms are not spoken of very often as the concept can somewhat be hard to grasp.

They literally rule our lives, they are with us throughout the day and part of the majority of things we do. Algorithms which I like most are those which are used to predict, whether it's recommending something or used in a game. It just makes life easier.

Netflix is something of which my brother uses, where you can view your favourite television programmes and films. Netflix is also known for their different algorithms (Kevin Slavin, 2013).
  • Cinematch
  • Dinosaur Planet
  • Gravity
  • Pragmatic Chaos
These algorithms were made to get an idea on it's users, using these mathematical equations it's able to get an idea on what it's users may want and creates a recommended list for them. A recommended list which is so successful in fact "about 60 percent of Netflix subscribers select movies based on these recommendations" - (Netflix Consumer Press Kit, 2013).

Spyware had installed itself onto my computer recently without my knowledge. The spyware, known as Price Companion, was for an algorithm which shared a similar function to that of Netflix, and upon rollover looks for a similar product to the item you are currently browsing.

I had however, found that the algorithm used on the spyware was quite useful as it found me products which were the same but of a different colour. Something of which I was very interested in.

How the spyware had reached downloaded itself on to my computer without my knowledge was most likely from another algorithm caused by a pop-up.

Algorithms are not just used as recommendations and those a like, but also for other tools which give off the impression you're somewhat psychic. Akinator (2013) for example...

By answering a small sample of his questions, Akinator - the web genie, is able to guess who you are likely to be thinking of. Of course, it is limited to some extent and can guess only those who are well known publically.

"Akinator uses the program Limule published by Elokence.com. The algorithm we use is an original creation" (Akinator, 2013) and the rest is stated as a secret.

Upon doing research, the type of algorithm which fits best is known as a Tree Match Algorithm (Siam, 2013). As suggested in the title, you could imagine this as a sort-of family tree. In the case of Akinator, this would work by using information used from previous sessions, storing it in it's database and acting off what it knows progressing you down the tree following routes upon which answers you clicked.

As a website which has quite a following, the positive correlation of the more users - the higher the guess accuracy, Akinator have proven to have very high success rates.
