It looks like HN doesn't like metaphors :) Since it's flagged, I will repost with a different title.
People are reacting to the clickbait title, not the use of metaphor. As the submitter, you should be able to change the title of the submission. If you no longer can, contact the mods via the Contact link in the footer so they can update it on your behalf.
Continuing to submit a post tweaking the title to improve it's chances can be viewed as spamming, particularly as it appears that you're also the author. Please don't do that.
Self-sustaining?
Nope.
Chemical reactions?
Definitely not.
Capable of extracting energy from its environment?
Unless you count people plugging in GPUs as the Blockchain's doing, no.
Darwinian evolution?
Hell no.
Overall conclusion: No.
