Can you guess the word?

Metal limbs. Metal skin.
Even our hearts - metal.
Can we feel the emotions? The emotions that humans keep?
Ha! Of course we can. We are mechanical, yes, but we have AI.
And, of course, we've got PLANS for your planet. Big plans.
Not to alarm you, but there might not even be space for humans on there...
If you do die out, don't worry. The colour shan't be drained.
Can you imagine it? A sprawling planet, full of mechanical creatures, of all colours and patterns...
An entire city, covering a planet... a mechanical paradise... Well.
Later. I've got to go and plan... Plan your destruction, that is.
