(sorry of quoting you...)
I think you have a point; maybe bigger brains or only a temporary advantage, but not the real 'purpose' of evolution (if evolution already has a purpose of course...). (or also... maybe it's not the amount of the brain that is important but rather the quality of its connections...)
Maybe I have to take back what I said of human species will still evolve in long term... Bigger brains is what science has present observed in relation to a bit earlier... it's just showing the tendency which is happening... I think it doesn't prove our species will survive for ever... (It might be that they don't)
On the other hand I doubt a bit whether evolution is unhealthy... maybe it's unhealthy now because it seems to have evolved to a species which sometimes acts in an unhealthy way... but maybe our species won't survive the consequences and then evolution will start over again in an other way... (just like with the dinosaurs...)
But our species seems to be able to do lots of healthy things also... but maybe the consequence of luxury and even health itself, is that it's unhealthy for the species...
Think of antibiotics... what happens... in long term bacteria become resistant... (they evolve) So we not other antibiotics... (they evolve again)... Bacteria in long term become more and more virulent...
What do we do? Maybe we kill all bacteria all at once?
Or does the human species have to discover some new kind of treatment for virusses???
Maybe species will adapt to toxines and evolve like this...??
Toxines seem to be a problem for us... but will it remain??
Anyhow whether it's nature's 'purpose' that we survive or not...
We made a choice... we want to survive... and our species will do everything possible to do this (even when we are a part of nature).
(PS: you seem to use very much of your brain...)
