Big Tech Wants to Harvest Your Thoughts

Big Tech companies are seeking to harness the ability to read and manipulate human thoughts, as demonstrated by recent advancements in neuroscience. Researchers have found that by using high-contrast patterns of dark and light bars, they can activate specific neurons in the visual cortex of mice, effectively controlling their behavior based on the images they perceive.

This has led to the idea that similar techniques could be applied to humans in the future, potentially revolutionizing the treatment of paralysis and other neurological disorders.

The breakthrough came when researchers implanted images of moving bars moving up and down into the brains of mice, which prompted them to drink water. Similarly, when bars moved side to side, the mice ceased drinking. By projecting these images directly into the mouse's brain using a series of laser systems, scientists were able to control the rodents' actions without showing them any visual stimulus.

These findings have significant implications for the future of human thought manipulation. Over the past two decades, researchers using functional magnetic resonance imaging (fMRI) have been constructing detailed maps of the mammalian cortex, enabling them to identify the neural representations of various emotions and thoughts. Advances in machine learning have allowed for the creation of algorithms that can analyze brain activity and reconstruct images, sounds, words, phrases, and even entire sentences.

In 2023, a paralyzed woman named Ann Johnson regained the ability to speak after researchers implanted a grid of 253 electrodes on the surface of her brain. The electrodes translated her neuronal signals into real-time sentences at a rate of 78 words per minute, using an animated avatar of her head to express her thoughts and emotions. While this technology holds immense promise for those with paralysis, it also raises ethical concerns about the potential misuse of such powerful brain-computer interfaces.

The more invasive the recording equipment, the richer and more detailed the data obtained. Although surgical interventions are rare, with fewer than 100 individuals worldwide having brain-computer interfaces, there is a growing trend of translating brain scans into words and sentences using fMRI and AI models. As researchers continue to push the boundaries of this technology, the potential to interfere with human thoughts and manipulate cognitive processes becomes increasingly plausible.

This poses a significant challenge for society, as the power to control and influence human minds is unprecedented.
