The end game here is developing a mind reading device. The endeavor device is ethically questionable because such a device would have a lot of ethically wrong/questionable applications.
Yeah, that's just what we need: brain scanners purported to "expose the unethical". Nothing could go wrong with that.
I find it extremely silly when people argue a technology is value neutral and humans are the problem so we shouldn't "judge" or critique the tech. Who do they think is going to use the technology?
