What is Neuralink?
Neuralink is a neurotechnology company founded by entrepreneur Elon Musk in 2016. The ultimate goal of Neuralink is to merge humans with artificial intelligence (AI) in a way that can enhance human cognition and communication.
The company’s mission is to develop brain-machine interfaces that can be implanted in the human brain.
How does the Neuralink work?
Neuralink’s technology implants tiny electrodes into the brain to record neural activity and stimulate neurons. A device wirelessly transmits the data to an interpreter, enabling control of a computer or prosthetic device and potentially restoring cognitive function. Video from Neuralink shows the brain chip demo by Elon Musk.
Why do the electrodes need to be directly connected to the brain?
Non-invasive techniques such as EEG can measure neural activity, but they have limited details. It’s like listening to a sports event from outside the stadium. Placing electrodes inside the brain is necessary to obtain individual neuron’s action potentials and access fine-scale information.
Funds raised by Neuralink from 2017 to 2021.
Neuralink has raised a total of USD 363 million in funding over four rounds. Raison participated in the fourth funding round held on December 7, 2021, which raised an undisclosed amount.
The market valued the brain-computer interface at around USD 2 billion in 2020 or 2021 and is expected to grow at a CAGR of around 14% from 2021 to 2030, reaching around USD 9 billion by 2030.
Cost estimation of Neuralink on launch and in future.
Neuralink has not yet announced the official cost of its brain-computer interface device or the surgery to implant it. However, Elon Musk has said that he expects the surgery to cost around a few thousand dollars and that it will be done by a robotic surgeon.
Interview by Elon Musk shows the estimated cost for the surgery it would be in near future.

The potential for Neuralink to enhance human cognition, memory, and communication.
One of the important potential applications of Neuralink is to enhance human cognition, memory, and communication. Neuralink aims to achieve this by developing brain-machine interfaces that enable communication between the brain and external devices, such as computers and smartphones, in a more direct and seamless way than is currently possible.
Neuralink’s technology has the potential to enhance human cognition, particularly for individuals with cognitive disabilities such as Alzheimer’s or traumatic brain injury. The technology may restore lost cognitive function by repairing damaged neural pathways or creating new ones. Additionally, it may help individuals with attention deficit disorder (ADD) or attention deficit hyperactivity disorder (ADHD) to improve their focus and concentration.
Neuralink’s technology could aid individuals with memory loss from brain injury or disease by creating artificial memories or accessing the brain’s memory centers more directly to help recall existing memories. This could potentially improve memory function for those affected by brain injuries or diseases.
Neuralink’s technology has the potential to revolutionize human-machine communication by enabling more efficient and effective communication. It could allow individuals to control devices with their thoughts or transmit information directly from the brain to other devices or individuals. For those with speech disabilities, the technology could provide a means to communicate more easily by bypassing traditional speech pathways and transmitting thoughts directly to a computer or device.
Reversibility and Upgradability of Neuralink brain chip on animals.
In a demo video, Elon Musk has explained how the pig named Dorothy reacted to the brain chip removal. Dorothy has no side effects due to Neuralink brain chip removal.
FDA approval for implanting Neuralink brain chip in humans.
In early 2022, Elon Musk’s Neuralink applied for human trials of their brain-computer interface device, but it was denied by the Food and Drug Administration due to multiple concerns. Neuralink’s employees are currently working to address these issues.
As Elon Musk mentioned in a conference, the Neuralink company is expecting to implant the brain chip in human at the end of 2023 with the FDA approval, which is not a confirmed news yet.
What are the ethical implications of merging human brains with artificial intelligence (AI).
- Control over the brain chip
- Equality to those who don’t have brain chip
- Privacy concerns
- Safety factor
- Long-term consequences
Control: Will humans maintain their agency and autonomy, or will they be subject to the influence of the AI they are connected to? This has the potential to greatly impact human rights and dignity.
Equality: Another concern is the potential for such technology to create a new class of “enhanced” humans who are superior to those who do not have access to such technology. This could exacerbate existing inequalities and create new forms of discrimination.
Privacy: There are many privacy concerns in adding a chip in human brain, particularly if the technology allows for the direct access and manipulation of individual’s thoughts and emotions. This could open up the possibility of unauthorized surveillance and control.
Safety: On Safety as a factor, if the technology malfunctions, it could potentially cause physical harm or even death to the person connected to it. Additionally, there is the risk of AI turning against its human counterparts, either through malice or due to unintended consequences.
Long-term consequences: Finally, there is the question of the long-term consequences of merging human brains with AI. It is difficult to predict what the impact of such technology could be on society as a whole, and what unintended consequences may arise.
What are the challenges of developing and implementing Neuralink?
- Technical Challenges
- Health concerns
- Regulatory issues
- Social accpetance
Technical challenges: One of the main challenges is developing the technology itself. This requires advanced technologies such as microfabrication, nanotechnology, and advanced robotics. Additionally, brain complexity poses scientific challenge to understand its workings and interactions with external devices.
Health concerns: Implanting devices in the brain raises significant safety concerns, such as the risk of infection, inflammation, or damage to surrounding tissues. It is also unclear what the long-term effects of having a device implanted in the brain might be.
Regulatory issues: Neuralink’s development requires navigating regulatory environments, including FDA approval and ethical human experimentation. There are also questions about who will own the data generated by the device and how it will be used.
Social acceptance: Two concerns surrounding BMI are the possibility of altering human identity and behavior, and access to the technology.
To address these challenges, brain-machine companies must invest in R&D, collaborate with regulators, engage stakeholders, and use tech ethically.
