Scientists are using stem cells, which can be programmed to grow into kidney cells or heart cells or, in this case, brain cells. They're called "organoids" and they're being used in an emerging new science called biocomputing, where they're paired with electronic circuity, yielding vast computing power.
Medical ethicist David Prentice says there are ethical and unethical ways to harvest stem cells.
“Organoids can be made out of embryonic stem cells, induced pluripotent stem cells, or adult stem cells,” he said.
Only the last two types don't require the destruction of a human embryo. Scientists say these chimeras will be needed to provide the power needed for a world run by AI. Prentice says there's some science and some fiction in that type of computing.
“They're not really relying on energy produced by these organoids or these cells in culture. It's not that it couldn't ever become a concern, but I think it's a long shot at this point,” he said.
What he is worried about is what happens when the stem cells are allowed to differentiate into brain cells which multiply and grow.
“When it comes to brain organoids there is a distinct concern that if you let those grow a long time, will they actually achieve enough brain cells together that they might achieve consciousness?” he asked.
