Transcript 1st Nobel Forum Mini-Symposium on Nanotoxicology

Nanotechnology
Catastrophe
Scenarios
Vedrana Novosel, Viraj Sapre, Szu-Chia Lu
Definition
We are drawing from science fiction,
research, and speculative articles to find
scenarios of world destruction caused by
nanotechnology.
2
Example
K. Eric Drexler’s coined the term “gray goo”
in his book “Engines of Creation,” referring
to the scenario that nanotechnology is
used to build self-replicating machines
which consume all of Earth’s matter
3
Notable Aspects
•
•
•
•
•
Biohazards
Sentience of Nanobots
Self-Replicating Nanobots
Human Misuse of Nanotechnology
Environmental Damage
Note: there are some overlaps between these scenarios
4
Biohazards
• Plague
– “Queen City Jazz” chronicles life after a
destructive nanotech plague
– In the “Plague Year” series, nanotech
supposed to cure cancer by dismantling
specific cells, dismantles everything
• Exposure to nanotech particles
– Researchers speculated that exposure
could cause cardiovascular disease at
the 1st Nobel Forum Mini-Symposium
on Nanotoxicology
5
Sentience of Nanobots
• Ability and desire to destroy humanity
– In “Prey ”, nanobots exhibit intelligent, predatory
behavior, attacking and killing animals by:
• tracing tracks
• suffocating their prey by blocking the bronchial tubes
• tripping their prey by making the ground slippery
• Mind control
– In “Prey”, nanobots can devour and take over their
hosts, initially affecting their decisions and then
controlling them, while allowing them to travel
and contaminate others
6
Self-Replicating
Nanobots
• “Gray goo”: out-of-control self-replicating robots
consume all matter on Earth while building more
of themselves
– First stated by Eric Drexler in context of
nanoscale assemblers
• Nanotech plants
• Could out-compete real plants, crowding the
biosphere with an inedible foliage
• Omnivorous nanotech bacteria
• Could out-compete real bacteria and reduce
the biosphere to dust in a matter of days
7
Human Misuse of
Nanotechnology
• Nanotech
weapons
– Nanomite warheads are used in “G.I. Joe: The
Rise of Cobra”
– Could lead to a destructive arms race as
described in a paper from the Foresight
Conference on Molecular Nanotechnology
• Economic and social disruption
– The Center for Responsible Nanotechnology
warns of artificially inflated prices and an
abundance of products due to molecular
manufacturing
– Opportunities for world dictatorship mentioned
at the Oxford Catastrophic Risks Conference 8
Environmental Damage
• Nanomaterials are not inert
– EPA study found that nanoparticles are
showing up in the livers of research animals,
can seep into living cells, and perhaps
piggyback on bacteria to enter the food chain
• Nano particles could damage the cells of living
organisms
– Causes ecosystem and biosphere destruction
• Pollution
– “Nano Litterbugs” article warns of nanoscale
pollution that we wouldn’t be able to get rid of
9
Why Is This Important?
• Scenarios from fiction hint at society’s
views about nanotech
• Help to determine how science should
proceed and about what we should be
cautious
• Inform decisions about regulations and
policies
• Speculate on how we can protect
ourselves and our planet
10
Further Research
• Feasibility of these scenarios (fact vs.
fiction)
• Technical details
• How far into the future?
