A neat idea and scene, very desperate and bleak. That first sentence should just be two sentences, something made worse by it ending with a preposition.
And I think you mean beneficiaries at the end there, not benefactors.
Overall, a great story idea robbed of a lot of strength by the technical side of things.

Thanks for the comments – yes, both of those are sloppy and I’ve tidied them up – teaches me to read back over something I’ve written in haste :) A few more subtle changes here and there to hopefully improve the readability too…

“They carry weapons, and they know if you’ve been bad or good.”

Love the concept and the bleakness.

The end of the end of the world (or is it the beginning of the rebirth?) is signaled by dogs barking at the carcasses of dead robots.

Very bleak, yet somehow offering a glimmer of hope.

When’s the movie coming out?
