When thoughts control machines
- Current BrainGate clinical trials have enrolled 13 participants who successfully control cursors, prosthetic limbs, and robotic arms using sensors placed in the motor cortex to decode intent to move.
- Existing brain-computer interface (BCI) technology is limited by its ability to record only a few hundred neurons, compared to the human brain's 85 billion neurons.
- The U.S. "Brain Initiative" was established as a $6 billion fund to develop tools for mapping and manipulating entire neural circuits to treat neurological and mental diseases.
- In 2017, a team led by Professor Raphael Jus successfully recorded activity from every neuron in a hydra (a simple freshwater organism) and demonstrated the ability to manipulate its behavior by writing neural codes.
- Kernel, a startup founded by Brian Johnson, is operating with $100 million of personal funding to develop neural interfaces aimed at radically improving human capabilities.
- Elon Musk's company, Neuralink, and DARPA are actively developing BCI technology to connect humans with computers and enhance military or human performance.
- A primary ethical concern involves "neuroprivacy," specifically the risk that internet-connected brains could expose the private contents of thoughts rather than just data.
- Experts warn that equitable access to BCI technology must be ensured to prevent the enhancement of human intelligence from becoming the exclusive domain of a privileged few.
- There is a stated imperative for society to co-evolve with artificial intelligence to prevent a capability gap where humans are outpaced by the machines they create.
- While the "Matrix" scenario remains distant, researchers assert that the technology for direct brain-to-internet connectivity is advancing rapidly enough to warrant immediate serious consideration of societal implications.
- The immediate medical goal of implants is to restore function or independence for paralyzed individuals by tapping into native brain motor control areas.
- Future applications anticipate "reading and writing" the neural code in humans, potentially allowing for the input of thoughts or the modification of behavior, though the human brain's complexity presents a massive current technological hurdle.
