Overview:In a few years, technology will merge with our bodies in ways that today seem unimaginable, and will redefine the limits of what is a human being. There are already people who, driven by the desire to experiment, have crossed the biological limits by introducing electronic devices that provide them with capabilities that go beyond what is "normal." They are the first hybrids, and they face the reaction of society, which goes from malignancy to enthusiasm. Today they are only a small minority, and many people consider them as disrupted experimenters, but in the near future we may recognize them as pioneers.
