Except that is not what I posted.
That's true, but it would be both foolish and dishonest to presume that this consensus correlates with the truth of existence. Because we are just as prone to collective bias as we are to individual bias.
All it really does is create the illusion in our minds that we "know existence" when we don't, simply because we can recognize something about how physicality functions and can manipulate it. But we humans will happily accept this delusion over having to face the enormity and significance of what we don't know, for the comfort it brings us.
And looking at it with an unbiased eye; one that considers other aspects of our existence besides physical functionality, it's not a very good track record. In fact, it's a bit if a dismal failure apart from this. Which is why the scientism crowd ignore all other aspects of existence but physicality as 'immaterial'.
We don't need better medicine so rich people can live longer, or better guns and bombs and delivery platforms so we can kill each other easier. We don't need more entertainment or communication distractions feeding us ever more believable lies. And we don't need to be spending billions exploring outer space. We don't need more "objective intelligence". What we really need is more SUBJECTIVE intelligence. More WISDOM, not more knowledge. And that's not going to come from science. It comes from philosophy, and from art, and from religion. THESE are the areas we need to be focusing on right now, and in which we need to be trying to make advances. The combination of science and industrialized greed is killing us. And will kill us all if we don't find a way to stop ourselves being turned into raving self-destructive idiots by it.
You want more wisdom, more subjective intelligence, but how can that be accomplished without a factual understanding of human behavior and all the factors that influence it? The problems you describe are not those of science or industrialization, they are the problems derived from our innate instinctual behaviors, our inherited human nature. We are simply born with them and every generation has to come to terms with a population of individuals pre-wired to function in small bands of hunter/gatherers. Fortunately, we are malleable, adaptive creatures, with a capacity for reason and an ability to override reflexive instinctual responses.
I don’t see that we are killing ourselves either faster or in greater relative numbers than we have in the past. I would argue the reverse actually, and attribute the reversal to our ever growing understanding of ourselves and the Cosmos we live in. We are collectively wiser than our ancestors, just not uniformly so. I would argue that hanging on to antiquated belief systems born out of a more ignorant past contributes to that disparity.
If you want a better world, we have to come to terms with the reality we actually have, not the one we imagine exists.
