Imagine the human as a living, interconnected system.
Information, emotion, memory, capacity, behavior, relationship, and experience move throughout it.
The Human Superhighway is the connectivity within that system — the routes through which more of the human can become available to more of the human.
Some connections are heavily traveled. Some become difficult or temporarily unavailable when conditions change. New roads can develop. Existing roads can become easier to travel. Alternate routes can become available.
Access can change without the underlying capacity disappearing.
You can have a six-lane highway of self-awareness that dumps directly onto a dirt road of boundaries.
That isn't failure. Human development isn't uniform.
