Every December the online intellectual salon called Edge,
presided over by literary agent John Brockman, asks a select (virtual)
assembly of scientists to ponder a question, such as what they are
optimistic about (2007), what “dangerous” ideas they have (2006) and
what they believe is true but cannot prove (2005). As the bell tolls on
2008 and rings in 2009, Edge is unveiling this year’s: “What game-changing scientific ideas and developments do you expect to live to see?”
As usual, the
offerings vary as much in quality as a cheap spumante does from Dom
Perignon. Predictably, contributors foresee space colonization and the
discovery of intelligent life elsewhere in the universe. More
intriguing, there are predictions that a new human species will evolve
from Homo sapiens, and that we will discover how to identify
the brain pattern that indicates a person is about to commit a violent
act (and will also discover how to suppress that pattern).
Read them yourself, but here are a handful that will give your brain a good workout to start the New Year:
*Harvard psychologist Howard Gardner foresees a day when it will be possible to “delineate
the nature of talent.” Genetics will reveal whether “highly talented
individuals have a distinctive, recognizable genetic profile,” while
neuroscience will show whether there are “structural or functional
neural signatures” of talent. As for the game-changing part (especially
in a society where people have the delusion that everyone is equally
talented, or can become so), imagine what happens if these signatures
can be recognized in infancy.
*Physicist Freeman Dyson of the Institute for Advanced Study imagines the development of “tools
to observe and direct the activities of a human brain in detail from
the outside,” making possible “observation or control of a brain.”
Since microwaves travel through brain tissue, putting a microwave
transmitter inside a brain would let its activity be sent to the
outside world, making possible what he calls “radiotelepathy, the
direct communication of feelings and thoughts from brain to brain.”
Change everything? Oh yeah. Radiotelepathy could be used for good or
for evil, Dyson writes, “a basis for mutual understanding and peaceful
cooperation of humans all over the planet . . . [or] a basis for
tyrannical oppression and enforced hatred between one communal society
and another. . . . A society bonded together by radiotelepathy would be
experiencing human life in a totally new way.”
*Neurobiologist Leo Chalupa
of UC Davis looks forward to the day when science can restore the
plasticity of the adult brain to what it was in early childhood. If
“the high degree of brain plasticity normally evident only during early
development can now be made to occur throughout the life span,” he
writes, it would be “a game changer in the brain sciences. Imagine
being able to restore the plasticity of neurons in the language centers
of your brain, enabling you to learn any and all languages effortlessly
and at a rapid pace. The restoration of neuronal plasticity would also
have important clinical implications since unlike in the mature brain,
connections in the developing brain are capable of sprouting (i.e. new
growth).”

Neurologist Marcel Kinsbourne
of The New School foresees the dawning of cosmetic neurology (a term I
prefer to his “neurocosmetics”), in which healthy people transform
their brains much as people now transform their bodies with cosmetic
surgery. “In some form, deep brain stimulation will be used to modify
personality so as to optimize professional and social opportunity,” he
writes. “Ethicists will deplore this, and so they should. But it will
happen nonetheless, and it will change how humans experience the world
and how they relate to each other in as yet unimagined ways.”
