Thoughts
wander in VR
Devices that allow for direct brain-computer communications
are advancing on two fronts: devices implanted in the
brain, and external electrodes that pick up the brain's
electrical signals. In general the external devices are

computing gets chipped
DNA computers can simultaneously check many possible
answers to large problems like determining the best possible

"If
we consider the fate of New Orleans with Hurricane
Katrina, we can certainly see challenges for technology
in terms of better design and maintenance of levees,

bright dedicated people to make use of it), and
acceptance of a status quo in which too many people
live in poverty."
