You know, I hadn't even thought of that! You could imagine one being placed on the brain to give us a boost. Looking at the picture again, they even look like the supposed alien implants some people have claimed they have inside them, weird.
I have to say, I don't know how I feel about biohacking, I was reading about an aussie guy (with an amazing name that I'll look up in a sec) who implanted his contactless chip under his skin so he could pay for trains with his hand. I love technology, and most sci-fi ideas don't freak me out, but that does. Equally, a bionic hand would be cool so I dunno...
I haven't seen that film in years! I know what I'm watching tonight now...
It does look like an alien implant!
