Keyart from my short story.
This species are revered as the W.I.S.E. men of the future. They have merged with the net and now serve as the vanguard for information. They suck up nutrients and are capable of photosynthesis. If you give them a trinket from the old world, they'll digitize it then they'd tell you a story. Whether it was true or not lay with the audience.
There's very few of them left. They decided they're a different species and now, after years of genetic tampering and ill-advised modification, they seem to have become one.
