Dangerous for the potential consequences we cant predict, and the violation of ethical considerations for a sentient organism.
We dont fully understand consciousness or how it works, and by experimenting with these, we could inadvertently create something capable of suffering or even self awareness. Without a clear understanding of these processes and how they work, it's downright reckless and unethical to assume theres no risk. Dbingham rightly points out that we're treading into unknown and potentially unethical territory.
We couldn’t predict consequences of most things, from wheel to eletricity to internet. People predicted mailmen on flying bicycles delibering mail to cloud houses. Best predictions were rare and still shallow. Still worked more or less. I don’t get this part at all.
I believe the most important part for ethics-concerned commenters here are ethics. But I have a hard time reasoning about it while living on a whole planet with (roughly) 90% of humans living under poverty line, 9.9% of humans living as modern-era slaves, and 100% of organisms that ever lived suffering in an incountable amount of ways. To me it’s more dangerous to leave this as is than experimenting on yet another 0.001% of biotissue.
Even when I try hard to take an ethical position, it seems moot to me. I still can’t be sure that my spinal cord isn’t suffering all these tears without me knowing. I mean yes, less suffering would be great, not even by ethics, just from empathy. But neural tissue that has no mouth and probably must scream is too effing everywhere to single some cell collections out. Nature doesn’t care. Scream if you can, and if you can not, too bad. I just can’t find this balanced view that you guys have, it feels pretty self patting on the back to me.
