I've always wanted to see a movie about the gray blob problem.
In the end humanity would win by reprogramming the bots but it is almost too late and 50% of earth has been turned into metallic stuff.

I'm hoping that we develop some pretty hardcore security technology before we develop nanobots. Barring that, I hope Australia develops nanobots first.

[Das Bruce]

Do some research, nanobots don't work like that.

I'm pretty sure the gray goo scenario violates the laws of thermodynamics.

I still like the orange ectoplasm end.

Basically the only thing that will save us from getting transformed into globulets of grey goo in a few years will be if the Large Hadron Collider kills us first.

With these scenarios we'd basically all be dead nanoseconds after realizing something went wrong. If Everything just instantly disappears, there'll be no one left to notice it's absence. So it's all good, rite?

care to expand upon the matter?

I realize this is rather informal, but I see turning a piece of unstructured material into a collection of self-duplicating nanobots as a rather extreme decrease in entropy; the laws of thermodynamics state, among other things, that entropy of an isolated macroscopic system never decreases (at least in any comprehensible timeframe). This would require at least a corresponding increase in entropy in an area that could affect the grey goo, and probably much more, as the environment is not specifically engineered to assist the grey goo.

(I am referring to the scenario where the grey goo consumes all matter.)

?

[knorke]

the nanobots will also need some energysource but maybe they could even build an eco system that re-uses material like plants and animals do with oxygen.

but the nanobots do not have to transform all matter.
even if they just transform the mount everest into a large rocket engine and blast earth into the sun, we are still fucked.
und alle so yeeaah.

Biological systems do exactly same Zerg. They decrease entropy locally while of course increasing it in overal through waste heat etc.

But there is nothing miraculous about self-replicating systems - you are one of them and most of the Earths biomass is in bacteria.

We could certainly engineer something like that. Though it would likely not be significantly more efficient than biological systems which had billions of years to perfect this, and would have to compete with biosphere. (So certainly not some miraculous instant spreading)

[Evil4Zerggin]

I was referring to the "all matter" scenario. Biological systems are far from consuming all matter--I believe less than 1 part per billion of the earth's mass is alive, not to mention how long it took to get here.

[Licho]

Yeah converting all matter is certainly nonsense, besides many of the elements/compounds would be useless or harmful for such self replicators.

The problem with nano-bots is they're so small that if the room is too hot, like say...above freezing, then they shake themselves apart. They need to work in the COLD.

So, you can stop any gray-goo with a something like...um...your hand. Or a flamethrower if you want to be more careful.

I'm pretty sure the gray goo scenario violates the laws of thermodynamics.

If you mean, in that it uses energy that apparently comes from nowhere, I refer you to The Matrix.
