Nanotech is turning us into mythical, god-like creatures

Nanotechnology or "nanotech" is the manipulation of matter on an atomic, molecular and supramolecular scale.

It is giving humans powers that previously could only be attributed to mythical, god-like creatures. These include for example:

holding your breath at the bottom of a pool for an hour (via red-blood-cell-replacing respirocytes)

allowing for reverse aging (via nanobots called chromallocytes that would insert fresh chromosomal material into your cells)

ending global warming (via solar-powered diamond trees that transform carbon dioxide into oxygen)

making materials that are 50 times stronger than steel for the same weight
