Organoid brain from a test tube will surpass computer LI due to intuition, scientists predict.

Published: 2023-02-28

According to a number of scientists, the passion for artificial intelligence based on electronics is a path with limited prospects. The evolution of terrestrial biological life has revealed to the world a perfect biological computer - the brain and the nervous system as a whole. A brain-computer artificially grown from biological material will be many orders of magnitude more efficient than any silicon platform, and a start has already been made.

"We're at a stage where the technology to build a biocomputer is mature," says environmental science professor Thomas Hartung of Johns Hopkins University. “We hope that some of the wonderful features of the human brain can be implemented in the form of OI [organoid intelligence], such as the ability to make quick decisions based on incomplete and conflicting information (intuitive thinking).”

Organelles are voluminous colonies of artificially grown cells. These can be cells of any human or animal organ, including nervous tissue. Any experiments can be performed on organoids without fear of violating ethical principles, although in the future one will still have to think about the risk of the emergence of consciousness in such structures. Until this moment, there are still many decades of the way, during which it will also be necessary to solve the issues of ethics in the treatment of organoid intelligence. However, ethical issues with "silicon" intelligence are also raised and they will also have to be addressed.

The prospects for organoid intelligence are evidenced by the simple fact that the capabilities of the human brain to solve a number of “intuitive” tasks were first surpassed by a supercomputer only last summer, which required a $600 million Frontier supersystem covering an area of 630 m2. A supercomputer needs millions of times more energy to solve “complex logical problems” than it would take to maintain the work of a brain that performs mental efforts of similar results.

Works with brain organelles demonstrate initial but undoubted success. The “brain” grown in a test tube was taught by Cortical Labs to play classic Pong. In other experiments, scientists were able to implant organoid cells into the visual cortex of the brain of mice, and they not only took root there, but were also able to respond to light entering the eyes of animals. Artificially grown nervous tissue has shown the ability to take root in the body, become its own (which will find application in medicine), as well as learn and work autonomously outside the body.

“It will be decades before we reach the [OI performance] goal of comparable to any type of computer,” said Hartung. “But if we don’t start laying the foundations for such programs today, it will be much more difficult to achieve this.”
