Ok, this technology is just freaky and rather scary in its potential. Apparently there is a way to replay the memories of the recently deceased, by hacking their brains, yo! I do NOT like this. If someone has passed away, let them be at peace. This is beyond invasive tech. I would consider this tech unethical.
