Starter, for answer, from the movie Alien One, starring Sigourney Weaver, Tom Skerrit and Yapett Koto.
Crew member to science offer Ash, at the site of the alien stuck to the face of one of the crew members.
>What's that tube stuck down there for.
Ash the science officer answers; Its feeding him oxygen.
This alien later goes on to kill almost the entire crew./

yfh said>Once a nanobot is made that can build copies out of itself out of relatively in-expensive resources, this will mark a turning point.

Phil answers> This is the problem, Bob Pete or whatever your name is, they don't know why and if nanobots should start doing this?
The problem is, that once a colony starts replicating itself, then this colony, is its own domicile, or mastery.
At this point in time, the self replicating nanobots, might look upon as any intrusion by man, as an attack placed upon its right to live.

yfh said> The nanobot's own computer could be reprogrammed using a wireless programming device, and once these self-replecating nanobot workers reached a certain mass, they could change what task they were programmed to do, and begin to process resources or build large nano-structures. Much like the many men who build the pyramids, nanoworker armies could build increadable tools that were, in fact, 'greater' the 'the wonders of the world'.

Phil answers > This is a little on the over-progress side of things.
The scenario is, that if nanobots, should become separate uncontrolled cultures, then to what danger and or effect, would these microcolonies pose?

I know that this sounds a little harsh, but there should be mandatory imprisonment, for people who hack into systems, and instill viruses.

yfh said> When will reprogrammable self-replicating nanobots be invented?
I don't know, but tell me when! =)
Phil answers> They already are, in cellular autominita, in the way viruses and bacteria communicate.

yfh said> What is the estimated time until self-replicating nanobot omniworkers are invented?
Phil answers, In every new invention, made by the hands of man, lies peril.

Notes, I think that the concept, that when cellular phones go nanotechnolgy, in micro, that a bacteria like computer virus, could be signaled to the nano-structure, is interesting.
What happens when micro-colonies are intoned with their own wills, remains to be seen.

Im glad that you have brought this information, to the forefront of our attention, yfh.

Our own bodies have self-replecating little parts, and the brain is like the communication/media/government all-in-one.

We are self-replecating micro-structures, naturally, but I guess what scares people is the idea of something superior to them destroying or dominating them.

When we think about competition, agression and war on earth -- we must remember that it is always about resources!

Humans only eat plants and animals because of what their bodies are made out of and fueled by.

If nano-life was introduced to earth, it would only consume what it was made of and what it was fueled by. Nano-life would have no reason to eat people OR plants if it did not digest sugars, protiens, etc.

If we where going to introduce a self-replecating and automatically evolving synthetic life form to an environment, I'd suggest we do that to the moon; not earth!

....still.... I'm a transhumanist. If there was a way that people made self-replecating nanobots that where fueled by and could be controlled by the human body, I'd have them put into me. I'd want to become un-natural. Neo-evolution. System-revolution.

If the nanobiobots where controlled by the human body, they would nolonger count as parasite, they would count as bodypart of highbred species.

Even if a crazey person releases nanobots in a virul way, someone else will release self-replecating nano-immune-systems that kill the intruders or something like that, I bet. I'm not affraid of the problems that come with new technology.

All it takes is some nut-case to unleash a nanobot that can communicate with and prepetually upgrade DNA in the same fashion as SAI before we see expotential genetic evolution that is nolonger generation based. Would that be so bad? Or would it be so good that it was scary?

I think all of these things work both ways.

I think that nuclear weapons are more dangerous then nanobots. Complexity is different then energy release.

I use to work in water purveying.

I know a little about the pollution problems, via this area.

One of the cute little chores that some companies perform, is dumping their industrial waste, into streams.This is, that they claim are only hot water, as it is too expensive, to get ride of this waste other ways.

As an example, when they built parts for the new stealth generations of fighters, on a govt res. they burnt what was left, giving their workers cancer.

They show the dumping process overhead, via flyovers, of how these companies, get ride of extra industrial waste, by simply flushing down the waste water tubes, into streams.

With these particles, in nanotechnology, as they are so resolutely fine, nobody really knows what will happen with them, when they are flushed into the environment.

What if some industry, dilutes and then flushes a drum full of not wanted nanospehres, into the storm drain.

What happens when these microsphere, combine, with say one of the creatures, such as some form of dinoflagelate, within a stream.

Already, the creatures DNA patterns are compromised, as in some way, this stream creature, might utilize some part of any nanotechnology micro product, as part of its makeup.

This is bound, to certainly happen.

You might end up with crayfish, that you would have to hit with a heavy object, to kill?

Or muskrats, that can bite through steel, as they ate the crayfish.

This goes on up the food chain, all because of one drum of micro materials dimpled into a streambed, via a noncareing industry.

What about battle?

Ultra-solider goes running at this objective, as twenty miles per hour, as he is a transformed, person under hidden agreements.
But he is hit in the middle part of his body, with an antitank rocket and cant repair.

It is a nighttime attack and they cant get the body, so it lies there in the desert for two days.

A carrion bird, starts to devour this body and the next thing you know, is that the animals that fed on the soldier, you must kill with a shotgun.

This stuff, if put into actuality, would become used, abused and dumped.

You might even have prostitutes in Europe somewhere, after have intercourse with a nanosolider, would have these colonies invade her body.

The press reports would go, (Athens prostitute arraigned, on attack of customer, by ripping of head:)

This is what your getting into, as these material, get used, abused and disposed of.

On or about Wednesday, Jun 08, 2008
I was standing out in my yard in NC.
I took a deep breathe and felt something hit the inside of my mouth.
It went straight to my throat. I could feel it circle my throat completely
and start down my throat circling the complete throat area. It proceeded down my throat toward my stomach area. I could feel it.
When it hit my mouth, it felt like one item but when it started down my throat it felt like hundreds of tiny objects in unison descending into my throat and downward into my body.

I think I had been hit with a self replicating Nano bot as that is what it felt like to me.
The sensation passed with in a few minutes as it made its way into my insides I stood there stunned waiting to see if I would fall or feel sick or ???

Nothing else happened and I went on about my business.I truly believe my body was invaded by a Nano bot that replicated itself immediately. I am not a nut I am a mother, grand mother, great grand mother, foster mother and much more. I have never before nor since experienced anything like this.
Can Nano bots be removed from ones insides?

If by some amazing feat self-replicating nano-bots were already a reality and were freely navigating our outside air for you to swallow, what makes you think that you would even detect its entry into your throat? By definition nano-bots are small beyond compare, what makes you think you could detect such an object any more than detecting a bacteria?

It is more likely to be pollen or a spore and will do you absolutely no harm at all.

I assure you that you have nothing to worry about.
