Backyard Brains Can Help Satisfy Your Inner Frankenstein (Video)
Did you know that cockroaches have such large nerves in their legs that you can poke into their legs almost at random and hit a nerve with an electrode so you can stimulate that leg with hip-hop music and and watch it move? And that you can easily order the parts to do this at home or at school? You can. And supplies to perform many other neuroscience experiments, too. Amaze your friends! Learn how neurons work! Gross out squeamish people! All that (and more) is what Backyard Brains is about.
If you stuck a venus fly trap for the same purpose, or you stabbed a maple tree for the purpose of making it bleed, is that also cruel? Practically everyone can see that it is cruel to do this to a human, while practically everyone can see it is not cruel to do this to do it to a plant. Somewhere between these, we went from cruel to not cruel. Is there a line, on one side of which is cruel, and on the other is not cruel, or is there a spectrum of cruelty here? And what property of these "creatures" makes it crueler to do so to some, than to others?
Cockroaches are not humans.
By your argument a neural network running on my computer also feels "pain" and our collective computer systems are the worst set of torturers to have ever existed.
