That's my opinion but be absolute undetectable is too dangerous when you live in a society, other cannot detect you then they cannot avoid an accident with you, just cross the road is too dangerous and if you have an accident, a deadly disease or some other things that need to get you an assistance there is no chance for you to survive. Just have a conversation is impossible, nobody can socially interact with you.
Apart if you love loneliness this isn't a good power
