Where have all those advanced led us? To self-inflicted extinction.
I think such a conclusion is not supported by an objective considerations of the evidence. First, we are, of course, not extinct. At least not yet.
I have conceded, as any reasonable person would, that science - in particular the application of science in the form of technology - has concomitant risks. Of that, there is no dispute. I think the big two are nuclear weapons and global warming.
But these risks can arguably be managed - we shall see, and I think this is an
open question; you appear to imply that our doom is certain.
On the other hand, science has
undoubtedly produced
huge benefits for humanity:
- medical technology: people are living longer and suffering less;
- dental technology: people used to suffer much more dental pain;
- transportation technology - we can travel almost anywhere in safety and at manageable cost;
- information technology - people have a wealth of information at their fingertips;
- understanding of the origin and evolution of the universe as a whole - findings from cosmology rightly elicit a deep sense of awe.
- etc., etc., etc.
Beware romanticizing the past - if someone really wants to go back to the pre-scientific age, they have not done their history.
For all our problems, life now is far, far better than it has ever been.
