Why human rights?
There are now close to a hundred sets of AI ethics principles. They name good things, fairness, transparency, accountability, and then leave you holding them. Each is a view of what AI ought to value.
None tells you whose view wins when a real decision is in front of you, whether you are building a system, or buying one for a school, a clinic, or a benefits office, and you need to know what it will do to the people on the other side of it.
Human rights offer something firmer to stand on, and something better to aim at.
They are the most considered account we have of what every person is owed, simply for being a human being: dignity, equality, a fair hearing, a private life, the chance to flourish.
They were written, after the worst of the last century, as a shared picture of how people should be able to live. That picture is not one opinion among a hundred. It is the common ground beneath them.
Build from there as the questions sharpen. Not “does this feel acceptable,” but: whose dignity does this system touch, what does each person have a right to enjoy, and what would it take for the technology to widen that enjoyment rather than narrow it. Human rights turn a vague unease into a clear question, and a clear question into something you can act on, design differently, demand of a vendor, or refuse to deploy.
