Recent advances in neuroscience have paved the way to innovative applications that cognitively
augment and enhance humans in a variety of contexts. This paper aims at providing a snapshot
of the current state of the art and a motivated forecast of the most likely developments in the next
two decades.
Firstly, we survey the main neuroscience technologies for both observing and influencing brain
activity, which are necessary ingredients for human cognitive augmentation. We also compare
and contrast such technologies, as their individual characteristics (e.g., spatio-temporal resolution,
invasiveness, portability, energy requirements and cost) influence their current and future role in
human cognitive augmentation.
Secondly, we chart the state of the art on neurotechnologies for human cognitive augmentation,
keeping an eye both on the applications that already exist and those that are emerging or are
likely to emerge in the next two decades. Particularly, we consider applications in the areas of
communication, cognitive enhancement, memory, attention monitoring/enhancement, situation
awareness and complex problem solving, and we look at what fraction of the population might
benefit from such technologies and at the demands they impose in terms of user training.
Thirdly, we briefly review the ethical issues associated with current neuroscience technologies.
These are important because they may differentially influence both present and future research
on (and adoption of) neurotechnologies for human cognitive augmentation: an inferior technology
with no significant ethical issues may thrive while a superior technology causing widespread
ethical concerns may end up being outlawed.
Finally, based on the lessons learned in our analysis, using past trends and considering other
related forecasts, we attempt to forecast the most likely future developments of neuroscience
technology for human cognitive augmentation and provide informed recommendations for
promising future research and exploitation avenues.
