When I first started researching this, I could hardly believe that it was true. A company in Switzerland known as “Final Spark” has constructed a bizarre hybrid biocomputer that combines lab-grown miniature human brains with conventional electronic circuits. This approach saves an extraordinary amount of energy compared to normal computers, but there is a big problem. The lab-grown miniature human brains keep wearing out and dying, and so scientists have to keep growing new ones to replace them. Stem cells that are derived from human skin tissue are used to create the 16 spherical brain “organoids” that the system depends upon. I realize that this sounds like something straight out of a really bad science fiction movie, but it is actually happening.
