Will the future belong to biological computers?
Organoid computers theoretically consume less space. In the future, these computers will have a three-dimensional structure in such a way that their cell density can increase significantly and more connections can be formed between neurons. Finally, although non-human computers are better at processing large amounts of data, the human brain is still better at making logical decisions, such as quickly identifying an animal.
Sokpal Singh Gill, assistant professor of electronic engineering and computer science at Queen Mary University of London, similarly assesses the potential of this type of computing. He considered energy consumption a major limitation for his computing. Artificial intelligence and Machine learning knows. On the other hand, human brain cells integrate such tasks with ease and have lower energy requirements so that they only need a small nutrient solution for proper functioning.
We have a long way to go before the dream of biocomputers becomes a reality. One of the important problems is the size. Organoids should grow from 50,000 cells to 10 million cells; But it is difficult to maintain this number of cells in a space larger than half a millimeter because oxygen and nutrients cannot easily reach their center. One of the solutions to this problem can be injecting or channeling fluids into the organoid.
Researchers must also find ways to communicate with the organoids to exchange information the way computers do. For this reason, improving their memory is vital. Brain organoids can currently only store short-term memories. For example, you can teach them to play pong, but they may forget everything the next day. The reason for this could be that the organoids lack microglia cells. These cells are a type of immune cells that appear in the brain and perform synaptic pruning, or the eradication of redundant synapses, so that the brain can continue to function normally.
There are also ethical questions about the creation and cultivation of brain cells and whether or not organoids are alive. Is it possible for them to develop some kind of consciousness or experience pain? Hartung and his team, in collaboration with bioethicists, are trying to evaluate everything in a way that does not cause moral harm.
