As much as I long for the day I get to see the world and myself be assimilated into grey gooey unity, the whole gray goo scenario is terribly implausible for the same reason why it has never happened despite having self replicating machines on earth for at least 3 billion years: it turns out that performing any kind of abrasion at that scale requires a shit tonne of energy, which entails an even larger shit tonne of heat.

Any grey goo candidates will rapidly vaporise themselves into cinders, even assuming they somehow manage to acquire the bordering-on-nuclear levels of energy density.

In reality, a crack team of specialised machines will always beat a sea of generics anyway so any swarm of artificial self replicators will inevitably balloon into a fully blown parallel ecology long before it acquired the bulk for Armagooden.
