Iron Man (avenger_2019)

I finally figured it out. It's like when they realized it was gonna be too expensive to actually build cyborgs and robots. I mean, the costs of that were impossible. They decided to just let humans turn themselves into robots. That's what's going on right now. I mean, why not? There're billions of us just laying around, not really doing anything. We don't cost anything. We're even pretty good at self-maintenance and reproducing constantly. And as it turns out, we're already biologically programmed for our little cyborg upgrades.
