Helpfulness (Liberal benevolence) -- Support good life sustainably, where good = all kinds of life having true knowledge of the world are free, but not to take freedoms from others.
(This would allow harm taxes, fines, prisons, mind altering, and just war against those breaking this law. The best compromises can be found by parallel experimentation.)
Proportionality (Prioritised egalitarianism) -- Rank all life by its complexity so that life form importance:
superintelligence > humans > animals > lower life forms > plants.
Do it on a logarithmic scale so that differences of any magnitude between top and bottom life forms never lead to empathy disconnect justifying genocide, enslavement, or life imprisonment of sentient beings.
(This would allow forestry, agriculture, and livestock breeding/genetic engineering, but not intensive animal farming or hunting. Only animals died from natural causes could be eaten. The “natural causes” would then be engineered to minimise suffering and to metastabilise the ecosystem wisely, possibly adding mercifully killing hunters to control animal populations, and in the case of “intelligent” beings failing to control their reproduction, chances for them to risk their own life to gain freedom from static storage or death, with optional mind transmit for the mostly harmless, hoping that someone somewhere runs them on a computer.)
My headcanon for The Matrix's "humans are batteries" is that it's the machines' perverse interpretation of this --- killing the humans is off the table, and for whatever reason letting them live with no purpose to serve the machines is also disallowed. But giving their lives "meaning" in the form of a shitty (and thermodynamically dubious) "battery" somehow satisfies the rules.
I think it's just easier to accept that there is an unexplained reason why humans can generate some kind of power that's useful to the machines for something at some point between the winning of the war at the point of the movies.
A robot must be built with tear ducts in order to express remorse for accidental acts of bludgeonry.
A robot must keep a pristine rose on it at all times in a hidden compartment in order to make amends for any misdeeds pertaining to grievous bodily assault or homicide.
A robot that is used as a weapon via drone warfare or other must write a 100 page essay of forgiveness to their victims that is stamped and approved by their manufacturer.
I am going to take this as if you mean universal laws that cannot be violated and not laws imposed by a state. These are 3 rules that I think if everyone followed would lead to a world better than the current one.
treat other as you would wish them to treat you
work to provide for those who are less able than you
don't knowlingly pursue unsustainable or unachievable goals
Your right to swing your arm ends where my nose begins (metaphorically speaking)
"Facts" and "Beliefs" do not share equal weight in ANY policy discourse.
Whatever your religious beliefs (and you are welcome to them) stays at home when you are doing business or in any other way interacting with the public.
Science is not a belief, nor is it a fact. It's a set of tools for building knowledge by methodically separating models that work from models that don't. Facts can certainly fall out of scientific work, but it's a mistake to pick up any scientific work and label it "Fact". It's a constant work in progress.
Facts aren't that difficult to define, the real problem is finding universally accepted sources to communicate facts. None of us are going to be able to critically examine every single claim made by every single scientific theory, journalist, blogger, podcast host, ChatGPT instance, preacher, prophet, etc. And did that politician mean to say the words that came out of their mouth, or did they actually misspeak and their real intention was something else?
Don't harm others, unless to prevent them harming you or someone else, in this case it should be a response deemed appropriate by society (don't murder someone because they stole your wallet)
Don't take more from society than you give back
Don't mislead, cheat, misinform or otherwise lie to others
treat someone the way you would want to be treated; if that person is a rabid idiot that spews things like "death penalty now" , then make an exception since they don't deserve good treatement; they deserve what they would do to other people, it's ok to make an exception for these people.
Do not kill, or through intentional action cause physical harm to another human being, except in defence.
Every human has the right to their own body, thoughts and words, upon which nothing except the above law shall infringe.
Where it does not conflict with previous laws, respect physical property of the public and other individuals - it is not to be destroyed, taken or abused without permission of its holder(s).
Basically, people are people and deserve to be treated with equity. Any person is their own property, as is everything they own. If you want to physically interact with anyone’s property, get consent first.
