What I want is to be able to choose if I want one or not. Before even considering it, it would have to come with extremely strong guarantees of privacy, open source, completely reviewed by many, tested for a couple of decades for safety, etc.
What I fear is that not having one won't be an option, it being required by society (not necessarily government) in one way or another, literally not possible to live without, and it of course being a complete ad-, surveillance-, "nudging"-, etc. filled system, always connected to HQ. I think this is the more likely outcome, like what has largely happened with smartphones.
