As a professional engineer of long standing (1967) I deplore computer modeling.
When did it come to be that scientists began to believe that the future could be foretold? Projecting forward into time from past data, no matter how accurate the past data is, will not and can not foretell what will happen at any future time.
All this is but a modern crystal ball, with the monitor being what is seen, and perhaps printed.
This planet rotates about its axis, and the world continues to change. In reality, in random ways.
Ego has often produced the most curious fantasies.
It is the celebrity culture we live in.
For some reason, people at large seem willing to believe that a celebrity is an authority. Hence they are willing to listen to some film star telling them how to vote.
A scientist is a form of celebrity within that context and once they step outside their own field they are no longer to be relied upon as being any more reliable or insightful than, yes, the man in the pub.
Perhaps they only associate the scientific method and ethos with their own field.
They can, outside that field, be as inclined to inspiration and intuition and plain silly thinking as anyone else.
There ought to be an embargo on anyone with the least taint of celebrity from speaking about anything other than their own speciality and even then, perhaps silence is golden.
The reality is that angst ridden Hollywood stars believe their Prius car is saving the planet (they don't worry where the electricity comes from and they don't belief studies which show that on an ashes to ashes basis a 4x4 comes top of the environmentally friendly list and Prius about 63rd) but their eco-sensitivity lets them create dangerously influential and misguided ill informed public declaration fully aware that it is their celebrity status that ensures "belief", and not any inherent truth in what they say.
Worse still, some of them become activists of the worst sort e.g. Ted Dansen with oceana.com
