We live in an era of accelerating change. Technology
is changing and innovating faster than most of us can keep up. And at
the same time, it's easy to get so caught up in shiny visions of the
future, and not notice the astounding things that are happening in
science and technology today. So the next time people ask you where the
future went, tell them it's already here.
Here are nine underrated or overlooked technologies that could transform
the world before you know it.

1. Cheap and fast DNA sequencing
Most of us know about DNA sequencing — but you probably don't realize
just how fast and cheap it's getting. In fact, some experts suggest that
it's following along a Moore's Law of its own. As Adrienne Burke has
pointed out, the speed of genome sequencing has better than doubled
every two years since 2003 — back at a time when it cost $3.8 billion
(i.e. the Human Genome Project). Today, thanks to advances in such
things as nucleic acid chemistry and detection, a company like Life
Technologies can process DNA on a semiconductor chip at a cost of $1,000
per genome. Other companies can sequence an entire genome in one single
day. And the implications are significant, including the advent of
highly personalized medicine in which drugs can be developed to treat
your specific genome. Say goodbye to one-size-fits-all medicine.

2. Digital currency
The idea of digital currency is slowing starting to make the rounds,
including the potential for Bitcoin, but what many of us don't realize
is that's it's here to stay. Sure, it's had a rough start, but once
established and disseminated, electronic cash will allow for efficient
and convenient online exchanges — and all without the need for those
pesky banks. Despite the obvious need for a distributed digital currency
protocol, the adoption rate has been relatively slow. Barriers to entry
include availability (it's in limited supply), the cryptography problem
(the public still needs to be assured that it's secure), the
establishment of a recognized and trustworthy dispute system (sensing
some opportunities here), and user confidence (a problem similar to the
one that emerged when paper money first emerged).

3. Memristors
Back in 1971, University of California at Berkeley professor Leon Chua
predicted a revolution in electrical circuits — and his vision has
finally come true. Traditionally, circuits are constructed with
capacitors, resistors, and inductors. But Chua speculated that there
could be a fourth component, what he called the memristor (short for
memory resistor). What sets this technological innovation apart is that,
unlike a resistor, it can "remember" charges even after power is lost.
As a result, this would allow the memristor to store information. This
has given rise to the suggestion that it could eventually become a part
of computer memory — including non-volatile solid-state memory with
significantly greater densities than traditional hard drives (as much as
one petabit per cm3). The first memristor was developed in May 2008 by
HP, who plan on having a commercial version available by the end of
2014. And aside from memory storage, memristors could prove useful in
signal processing, neural networks, and brain-computer interfaces.

4. Robots that can do crazy futuristic stuff
Today we have robots that can self-replicate, re-assemble after being
kicked apart, shape-shift, swarm, create emergent effects, build other
robots, slither like a snake, jump to the tops of buildings, walk like a
pack mule, and run faster than a human. They even have their own
internet. Put it all together and you realize that we're in the midst of
a robotic revolution that's poised to change virtually everything.

5. Waste to biofuels
Imagine being able to turn all our garbage into something useful like
fuel. Oh wait, we can do that. It's called "energy recovery from waste"
— a process that typically involves the production of electricity or
biofuels (like methane, methanol, ethanol or synthetic fuels) by burning
it. Cities like Edmonton, Alberta are already doing it — and they're
scaling up. By next year, Edmonton's Waste-to-Biofuels Facility will
convert more than 100,000 tons of municipal solid waste into 38 million
litres of biofuels annually. Moreover, their waste-based biofuels can
reduce greenhouse gas emissions by more than 60% compared to gasoline.
This largely overlooked revolution is turning garbage (including
plastic) into a precious resource. Already today, Sweden is importing
waste from its European neighbors to fuel its garbage-to-energy program.

6. Gene therapy
Though we're in the midst of the biotechnology revolution, our attention
tends to get focused on such things as stem cells, tissue engineering,
genome mapping, and new pharmaceuticals. What's often lost in the
discussion is the fact that we already have the ability to go directly
into our DNA and swap genes at will. We can essentially trade bad genes
for good, allowing us to treat or prevent diseases (such as muscular
dystrophy and cystic fibrosis) — interventions that don't require drugs
or surgery. And just as significantly, gene therapy could eventually
give rise genetic enhancements (like increased memory or intelligence)
and life extension therapies. Gattaca is already here, it just hasn't
been distributed yet.

7. RNA interference
The discovery of RNA interference (RNAi) was considered so monumental
that it won Andrew Fire and Craig C. Mello the Nobel Prize back in 2006.
Similar to gene therapy, RNA interference allows biologists to
manipulate the functions of genes. It works by using cells to shut-off
or turn down the activity of specific genes, and it does this by
destroying or disrupting messenger molecules (for example by preventing
mRNA from producing a protein). Today, RNAi is being used in thousands
of labs. It's becoming an indispensable research tool (to create novel
cell cultures), it has inspired the creation of algorithms in
computational biology studies, and it holds tremendous potential for the
treatment of diseases like cancer and Lou Gehrig's disease.

8. Organic electronics
Traditionally, our visions of cybernetics and the cyborg is one in which
natural, organic parts have been replaced with mechanical devices or
prostheses. The notion of a half-human, half-machine has very much
become ingrained in our thinking — but it's likely wrong. Thanks to the
rise of the nascent field of organic electronics, it's more likely that
we'll rework the body's biological systems and introduce new organic
components altogether. Already today, scientists have engineered cyborg
tissue that can sense its environment. Other researchers have invented
chemical circuits that can channel neurotransmitters instead of electric
voltages. And as Mark Changizi has suggested, future humans will
continue to harness the powers of their biological constitutions and
engage in what Stanislas Dehaene calls neuronal recycling.

9. Concentrated solar power
A recent innovation in solar power technology is starting to take the
world by storm, though few talk about it. It's called concentrated solar
power (CSP), and it's a massively distributed system for extracting
solar energy with mirrors and lenses. It works by focusing the incoming
sunlight into a highly concentrated area. The result is a highly
scalable and efficient energy source that is allowing for gigawatt sized
solar power plants. Another similar technology, what's called
concentrated photovoltaics, results in concentrated sunlight being
converted to heat, which in turn gets converted to electricity. CPV
plants will not only solve much of the world's energy needs, it will
also double as a desalination station.
