Wonderful thoughts Nipun ! It is interesting to see how we think progress / future as machinized human beings rather than divinized human beings . I once heard that evolution after nature made human beings, is not in the physical realm but now evolution happens in the realm of the mind and spirit. Only trouble is, this evolution is voluntary and needs our 100% effort . As you rightly point out unfettered technology in the hands of uncontrolled mind is dangerous and self destructive indeed ! Ultimately it boils down to this - it is easier to fix , buy control external bugs than the internal bugs. But what gives me hope and strange sense of confidence is that Nature/universe (as you call it ) and GOD (as i call it ) is always a few steps ahead and will lead us through .
