@JudyHelfrich I had a class on stem cells a long time ago where one of the topics we read about was growing human neurons in petri dishes. The neurons would clump into small spheroids and the cells would die from the inside out leaving a thin surface layer of active cells. I know there wouldn't be enough neurons for them to be thinking anything, but the image still sticks with me. What a weird existence, computing unknown patterns across the surface of a dead ball detached from the world.
