Creating human-level AI isn't an issue of processing power.
We've had for some time supercomputers that already possess greater processing power than the human brain, and that doesn't mean that they do anything more than crunch lots of numbers.
Human-level AI will be about organizing that processing power in a way that's similar to the human brain's functionality.
Regenerative medicine and reprogenetics are much closer on the horizon, and have just as much potential to transform society.


I agree with everything you said. =)

As far as regenerative medicine, that will be an interesting path. We are on the verge of "curing" the aging process. That doesn't mean by 2020, but certainly within our lifetimes.

That brings entirely new situations involving ideas like Social Security and the entire idea of "retirement", not to mention population growth and resource availability.

I totally agree that software will be the largest hurdle on the road to true "strong AIs", but I also think that when most people ponder the possibility of achieving that goal they are doing so in the context of our current technological tools. The leap we've had specifically in data mining has been incredible... Kurzweil spoke of Google Images as one of the main reasons why his computer program was able to teach itself how to distinguish between dogs and cats. We have so much information available to us today (and still increasing) that it is becoming increasingly possible to create learning AIs based on that information.

I don't think it will be terribly long before the same thing is done with medical knowledge, which will be very interesting when combined with voice recognition. The biggest hurdle will be teaching computers to understand the meaning behind what people are telling it, but that is an area of AI that is increasing rapidly as well. There are already programs for cell phones that can translate your speech into other languages. It won't happen overnight, but when you're talking about the current speed of technological progress, 2030 is not an unreasonable prediction for something like that.

seriously, wouldn't you rather be dead?


I think one's strategic perspective doesn't have to change in a situation like this. Her brain is normal, in contrast to an individual like this. Work hard/smart, contribute to society and the economy... people will want to help you. Eventually, regenerative medicine (stem cells) will be able to make her pretty.

The current problems in the world are insignificant in the long run.

We thought we were righteous in the 20th century for resisting the human sciences, but in the next couple of decades reprogenetics and regenerative medicine (stem cells) are going to begin fundamentally changing the human condition in favor of greater equality, personal choice, and freedom from disease.

Cheaper energy from advances in nanotech and solar power is set to arrive within 10 or 20 years.

Etc. Etc.

Seems to be missing one critical element, which is the controller that is found in many modern golf cart that allows for regenerative braking. Let off the throttle on a down hill or coming to a stop, and it spins up the motor sending energy back to the battery. It's a shame to burn it all of as heat and brake pads. I'd still like a go.

Fantastic video.
Imagine the possibilities if the concepts of the ultra-light weight car, the electric engine, the regenerative breaks, the solar cells on the roofs of cars, were all married together.

Why are we not on the path to acheiving this ?
You would think we would be agressivly pursuing this, but unfortunatley its all kept hidden in universities labs.

I'm STILL whinging about the sims.

But regarding halo, a rechargeable shield is simply an extra healthbar that regens itself.. so the innovation would be "regenerating health bars" which when put like that doesn't sound so innovative

That's not true. They have simply refused to fund research into infantile stem cells. That is not what this is.


Fair enough. I was generalizing a bit. Still an important issue to be considered because they are impeding on research that can potentially save lives and vastly improve the quality of life for many people. Just my personal opinion though, I know some people have a different view on when "life" begins (even though it's okay to kill hundreds of thousands of already born Iraqis overseas, just so long as we don't harm a complex cellular organism with no recognizable human features).

I believe their current engine uses LOX (liquid oxygen) and 90% ethanol. They have tried multiple different engine configurations and fuels, so after the LLC is won, they may spend more time looking into some other options again. Atm, they want reliability and stability from what they have working. The LOX chamber on the module is the bottom one, the other being fuel. The white coating on that tank is there as insulation as the LOX is obviously very cold, and the engine is not... Being so cold, LOX can be used in a regeneratively cooled engine design, where the LOX acts as a coolant for the engines throat before entering the engine itself.

I never really thought that not being able to swear on network television and radio was a bad thing. I don't think it should be a big deal. Entertainers should be clever enough to be funny without having to curse and be lewd? Take Brian Regan, for example.

That just great for you...but the FCC doesn't need to be involved for you to decide what you will watch and listen to or not. In my opinion Brian Regen is great...but so is South Park. Saying someone has to be funny without cursing is like saying someone like Britney Spears has to perform without lip syncing. That should be the viewers call and not the FCC.

"There is a difference between "stem cell research" and "embryonic stem cell research." Various conditions have been treated with some success with stem cells from adults. Literally nothing has been accomplished with stem cells from aborted feti. Opposing using embryos is not the same as opposing research or not caring about suffering."

First embryonic stem cells do not come from aborted fetuses. Second, name one disease or injury that has been cured by adult stem cells. Third, back to your argument that nothing has been accomplished with ESC, that is because thanks to Bush's restrictions, there are only a limited number of ESC lines available for research, none of which can be used in humans trials because they have become contaminated with other feeder cells.

"Amendment 2 would not criminalize stem cell research like Fox says it will."

Nobody said amendment 2 would criminalize stem cell research. Fox said Tenent supported criminalizing ESC research.

" Easily dismissed via . . . Wikipedia? Please. I'd also ask you to note the word "potential" in your own source."

So your against research that shows potential? The Wikipedia article is correct, but if you won't believe it, try this source from the NIH:

"Embryonic stem cells, as their name suggests, are derived from embryos. Specifically, embryonic stem cells are derived from embryos that develop from eggs that have been fertilized in vitro—in an in vitro fertilization clinic—and then donated for research purposes with informed consent of the donors. They are not derived from eggs fertilized in a woman's body. The embryos from which human embryonic stem cells are derived are typically four or five days old and are a hollow microscopic ball of cells called the blastocyst. The blastocyst includes three structures: the trophoblast, which is the layer of cells that surrounds the blastocyst; the blastocoel, which is the hollow cavity inside the blastocyst; and the inner cell mass, which is a group of approximately 30 cells at one end of the blastocoel."

"Blastocyst — A preimplantation embryo of about 150 cells. The blastocyst consists of a sphere made up of an outer layer of cells (the trophectoderm), a fluid-filled cavity (the blastocoel), and a cluster of cells on the interior (the inner cell mass)."

Also from the same NIH article:

"V. What are the similarities and differences between embryonic and adult stem cells?

Human embryonic and adult stem cells each have advantages and disadvantages regarding potential use for cell-based regenerative therapies. Of course, adult and embryonic stem cells differ in the number and type of differentiated cells types they can become. Embryonic stem cells can become all cell types of the body because they are pluripotent. Adult stem cells are generally limited to differentiating into different cell types of their tissue of origin. However, some evidence suggests that adult stem cell plasticity may exist, increasing the number of cell types a given adult stem cell can become.

Large numbers of embryonic stem cells can be relatively easily grown in culture, while adult stem cells are rare in mature tissues and methods for expanding their numbers in cell culture have not yet been worked out. This is an important distinction, as large numbers of cells are needed for stem cell replacement therapies.

Nice try, Gov. wallace - but that particular right-wing talking point is easily dismissed via Wikipedia:
http://en.wikipedia.org/wiki/Stem_cell#Embryonic_Stem_Cells

Embryonic stem cells (ESCs) are stem cells derived from the inner cell mass of a blastocyst, which is an early stage embryo - approximately 4 to 5 days old in humans - consisting of 50-150 cells. Embryonic stem cells are pluripotent, meaning they are able to differentiate into all derivatives of the three primary germ layers: ectoderm, endoderm and mesoderm. In other words, they can develop into each of the more than 200 cell types of the adult body when given sufficient and necessary stimulation for a specific cell type. When given no stimuli for differentiation, ESCs will continue to divide in vitro and each daughter cell will remain pluripotent. The pluripotency of ESCs distinguishes them from adult stem cells or progenitor cells, the latter two only having the capacity to form a more limited number of different cell types.

Because of their unique combined abilities of unlimited expansion and pluripotency, embryonic stem cells are a potential source for regenerative medicine and tissue replacement after injury or disease. To date, no approved medical treatments have been derived from embryonic stem cell research. This is not unusual for a new medical research field; in this case, the first human embryonic stem cell line was only reported in 1998.
