I'm still waiting to be able to augment my body... any day now.

I still want to know why a proper artificial eye is hard to do?  Everything uses external glasses or cameras and sh*tty resolution

[Voxr]

Because the eye is a rather small yet complex organ.

Seriously why can't they map a CCD to the retina pixel for pixel and then map that to the optic nerve if they can figure out how to translate the nerve signals?  Put the CCD just under the retina where it's defective.....

If they could, they would've done it a long time ago.

Yeah I know......

 

I'm just wondering as I was born with cataracts and had my lenses removed as a child..  Have had to wear very thick glasses ever since that to correct for that but have had implants a few years ago to replace the very thick glasses,  I was thinking something like this could help me..  When they removed my natural lenses they didn't put anything in place to replace them, hence the glasses and now lens implants which are attached to the iris..

Britain has a sauropod, and it's really old: http://www.scienceda...50601141523.htm

 

The sauropod species are my favourite dinosaur. Why? They're the biggest and yet vegetarians. I just love the irony in that.

Just slap on a Von Nueman architecture real time processing computer in your eye that processes graphics and gives an output without having any heating issues . See the problem here?

Yeah I see your problem....    Would it really need that much processing power?  And isn't a Von Neuman machine an AI?

Von Nueman architecture is basically the standard architecture used in today's computers. Depending on the amount of data it needs to process. You would have to

1) obtain real time streaming into eye
2) depending on the resolution, process stream data on the buffer
3)process data for output
4)send data to gpu (hardware or software based)

In a relatively real time environment. It would be very difficult to keep the heat low,especially of your software is dependent on speed

Ah ok ...... Points taken

 

 

For some reason I thought Von Neuman machines were an A.I. concept  my bad.

You are not off. Von Nueman did some work in Automata Theory(Logical Computers e.g. Turing Machines ,Push Down Automata, Finite State Automata)

 

He did some work on self replicating Automata

It's "only" 1000 times  , and we've seen a few steps like that before (anyone remembering 20MB harddrives?), so don't get your knickers in a knot. Still, it's another step forward.

"Von Neumann machine" is essentially the winning concept, the type that all general computers since after WW2 are. It's not exactly true, since the processors themselves have become so incredibly complex and striated. The modern CPUs, both in computers and smartphones, are today internally a hybrid between 'Von Neumann' and 'Harvard' architectures. Outside of the CPU, it's still sort of Von Neumann.

Because that's really, really, REALLY hard. The brain isn't a PC you can just plug an input in to. You are talking about taking a digital electric signal and converting it into a biochemical signal the brain will interpret in the same way, which is not how evolution designed the eye. It's designed to take light, send it through a million and one permutations to send into the brain, who then converts that signal into "seeing." Switching the input to be a digital signal means tricking the optic nerve to take a totally foreign form of input and still generate the same signal... very complex and something we are just now beginning to comprehend how to do (but which we are still decades away from accomplishing).

EDIT: Just realized there has been a whole conversation about this already.

BTW this was an interesting link. Not sure if I had posted it before on here..

I hate that Facebook page "I ****** love science" it's not even a science page. It posts mildly amusing memes and pictures, any actual scientific content is often stolen from elsewhere or titled sensationally for clickbait but garners less discussion than the actual memes overall.

 

I've got to agree with the article below that the page is anti-science:

Not quite, but I am aware of some research on psychopaths; moral psychologists and philosophers tend to be interested in them because superficially at least, they seem to be 100% as rational as you or I but are unable to make the kinds of moral judgments we make. This suggests that moral judgment is not a matter of reasoning. There are also other questions, like whether or not psychopathy is the kind of condition that should excuse wrongdoing. Here's a pretty accessible interview with philosopher Walter Sinnott-Armstrong on the subject.
