To some extent we already are or perhaps still do live like animals. Scratch the surface of most people and you get the lurking savage underneath. Do not forget that the vast majority of humanity is living day to day and in many places struggling just to exist. From time immemorial we have been trying to accumulate wealth and power at the expense of others, have we not? Mostly all we've done is find new ways and weapons to do it on a grander scale. Which is not to say as a species we have not devoted time and effort to find cures for diseases and study the sciences to improve the lot in life for a lot of people. It ain't all bad, but there's no doubt we haven't worked harder than we should have on the social aspects of science rather than the technological aspects that increase the standard of living but also create great wealth. It ain't like we can't do it, we got the smarts to stop wasting time, money, and blood on stupid wars and petty squabbling. But obviously it's going to take some time. A lot of time would be my guess, it could be that we're in a race to adjust our priorities before a major catastrophe that maybe could have been prevented wipes us out. Or most of us. But - we ain't ready yet to grow up enough. JMO.
