Elon Musk's brain-computer interface firm Neuralink has reached a groundbreaking milestone, successfully performing two brain-computer interface implants in a single day.

The revolutionary achievement, announced on 21 July via X, marks the first time the neurotechnology firm has conducted dual surgeries within 24 hours, bringing its total number of human participants to nine.

This move brings it closer to its ambitious goal of completing 20 such procedures by the end of the year, a development that has already caught the attention of Google DeepMind's CEO.

Neuralink's Milestone: Two Implants in a Day

Neuralink announced on X (formerly Twitter) that it had completed procedures on its eighth and ninth human participants.

Musk reposted the announcement, sharing his excitement that Neuralink had carried out two such surgeries within 24 hours for the first time. He also highlighted the transformative potential of Neuralink's technology.

The 54-year-old business magnate emphasised the profound impact it could have, suggesting scenarios where loved ones might regain their ability to walk or cognitively remember family members once again.

Early Successes and Ambitious Horizons

Neuralink has now operated on nine participants, including individuals with spinal cord injuries and those with amyotrophic lateral sclerosis (ALS). Reports indicate that participants are using the devices extensively, with some logging up to 100 hours of use each week.

In the future, the company plans to enhance the capabilities and reach of its brain-implant devices significantly. By 2028, it aims to integrate over 25,000 electrodes that can access deeper brain regions, potentially enabling the treatment of various neurological and psychiatric disorders, as well as exploring connections with artificial intelligence.

Google DeepMind Weighs In: A Broader Perspective

These developments haven't gone unnoticed by other prominent figures in the field, with Google DeepMind's Nobel Laureate CEO Demis Hassabis offering his perspective.

Reacting to Musk's tweet, Hassabis noted, 'An amazing technology!' This brief yet enthusiastic comment from a leader in artificial intelligence raises a compelling question, posed by Mashable: Is Google, through DeepMind, also venturing into brain-computer interface (BCI) technology?

Neuralink's Practical Progress

Neuralink's accomplishment underscores the growing effectiveness of its technology. This system is designed to establish a direct connection between the human brain and machines, thereby facilitating seamless communication.

Since 2016, Neuralink has been at the forefront of neural interface technology. Their recent progress shows promising steps toward putting this technology to practical use.

Neuralink's initial patient, Noland Arbaugh, a person with quadriplegia, received the first Brain Chip Implant (BCI) in March 2024. The now 30-year-old quickly demonstrated his newfound ability, using only his thoughts to move a cursor, control music, and play games.

The Path Forward: Human-AI Symbiosis

Since the initial successful procedure, Musk has asserted that Neuralink could eventually address various conditions, including blindness. However, the company's clinical trials and current methods have drawn criticism due to ethical concerns.

Neuralink's ultimate goal is to create a comprehensive brain interface that enables high-bandwidth communication directly between any neuron in the brain and external devices. This idea could lead to groundbreaking progress in how humans and technology interact, made possible by automated surgical procedures and quick activation after an operation.

Musk's overarching aim with Neuralink is to achieve symbiosis with artificial intelligence. His other venture, xAI, is actively developing cutting-edge AI technologies. The company recently unveiled Grok 4 AI and three AI companions, which have generated considerable discussion online.
