Artificial intelligence (AI) is a field that is evolving more and more and now scientists at Johns Hopkins University, in the USA, plan to create living computers using human neurons made in the laboratory from stem cells. The idea is something similar to the human mind to enhance the development of artificial intelligence.
According to the publication on the portal Frontiers in Sciencethe study was signed by 21 scientists specializing in their research areas led by biologist and engineer Thomas Hartung.
The technique uses cells collected from the skin or blood to create stem cells programmed to function as neurons called “brain organoids”. They are fixed on plates with electrodes and an artificial system to keep them alive while they process information.
Early studies have shown that brain organoids can perform some tasks and even play video games through early learning, but their potential may be greater. See what one of the project’s scientists said in an interview with Frontiers in Science:
We envision the creation of complex networked interfaces, in which brain organoids would be connected with sensors to capture the real world, with output devices, and finally connected with each other and with organoids of sensory organs (for example, organoids of the brain). retina of the eyes).
The idea is that neurons help make computers more efficient both in terms of AI and energy, as supercomputers already use up to 20 million watts to operate, while a human brain works with up to 10 watts.
While the idea is promising, Yuval Noah Harari, one of those involved in the study, told the magazine L’Express that science still needs to evolve and not all goals can be achieved at the moment due to technological limitations.
To give you an idea, an organoid the size of a grain of sand has regarding 50,000 neural connections, something difficult to be read by just one sensor, although this barrier can be overcome with optogenetics to facilitate communication between artificial neurons and real.
While nuclear weapons cannot invent more powerful bombs, AI can create exponentially more powerful intelligence. The crucial first step is to require strict security controls before these tools are released into the public domain.
One justification is that silicon electronic devices are even more powerful and resistant than brain organoids. In addition, the authors of the study propose that an ethics committee be created for the development of this technology that can even help in the treatment of neurological diseases.
