Musk is a wealthy, right-wing extremist who easily embraces conspiracy and is only out for himself. All American capitalists at that level couldn't care less about how their workers are faring in life. He's almost uncaring enough to run for office. Maybe 2028, for the MAGAQANON party.

Not really. We are still in the collecting data phase. There is the worry that bioaccumulation make chronic effects more likely, but so far there is no smoking gun publication (e.g. showing direct effects) nor is the body of evidence (IMO) strong enough to know about likely detrimental effects. Most evidence that I am aware of are basically showing potential associations or focus on components with somewhat better known detrimental effects (e.g. BPA). I.e. both rely on some level of extrapolation in terms of mechanisms or life-time exposure. That is not to say that there is no effect, but on the other hand there are many other exposures including "forever-chemicals" such as organohalogens, where potential toxicity is better understood. Also other exposures (e.g. air pollution) which are common but are known to be way more harmful. Microplastics in my mind is a bit of a "hip" topic, but compared to what we already routinely put into our bodies it is not really the most significant one (for now).

If I understand your question correctly... No, a model cannot describe anything to a fundamental level. A model is a representation of a system that describes the workings of that system in terms we can understand. It is not meant to represent "reality". Gravity is a force when talking Newtonian gravity, but not a force when talking about Relativity. Neither is "right" or "wrong" except in context of the model you are discussing at the time.

None of the models describe the "true" form of gravity. The models are useful approximations of what is "really" happening.

Thanks. Thank so much,

I don't know the first thing about this program, but it sounds to me as if it may use some sort of method of iterative approximation that converges towards a final value. If that is so it may be programmed to stop iterating when the difference between successive iterations falls below a preset level, or something. Could that makes sense?

Newtonian gravity is descibed as a force. GR is curved spacetime and Quantum Gravity has it mediated by graviton particles. GR comes up short below Planck level and QG comes up short at the macro level, so which level you look at determines which you use. This is the 'domain of applicability'.

The title statement is not true. Surely we don't need to exaggerate wrt the things McCarthy has said to make a point.

Jut the fact that computation happens, is my evidence. It is located on God's space ship.
