as to eugenics and so on
From the gist of what was written as response to the 'smartest' guy, one could say that if one were to control who reproduces then the 'advancement' of humans would be propelled forward significantly within only a few generations. To be kind, one could create a world where those that are not selected for reproduction are ensured that their lives are very enjoyable and worthwhile, as one does for those that have special wishes when riddled with cancer and are about to die (ofcourse am not meaning to be so dramatic in this comparison). Ofcourse low IQ people sometimes have high IQ children, as is evident, since none of us are presently chimps, are we? The IA has been increasing overall and some of those super high IQ people have very ordinary parents. Thus, one cannot discount those with low IQ from being potential parents. Perhaps a better way of 'fiddling' with nature would be to implement genetic engineering or blastocyst screening, to ensure that the result has a high IQ.
In a world where IQ would be, say, twice of what it is today, the world would become a different place. Perhaps most things would be automated or mechanised to free up people for positions requiring more thought. For instance, prior to inventions and designs of machinery mining was carried out by hand by people who may as well have been children; and infact they were. Advent of machinery in mining has led to the employment of people that have enough brain power to operate it safely, thus, no longer requiring a child at the end of a pike. The average IQ of people employed within that industry in that particular role, of digging, would have increased significantly over the past 200 years. We have seen the same movements within every area of industry and every path in life within the first world. There are some societies still around where this progress has not occurred and their average IQs are well below our modern average of 100. Ofcourse their 'average IQ' would have been our 'average IQ' perhaps 300 years ago.
The smartest man today will be an average man of the next century, perhaps. Although, it is not clear whether natural IQ has moved forward by that much or whether it is a function of cramming knowledge and thereby expanding the mind as part of education. There could also be biological limitations on natural IQ, brain size could be one of those, however, it is not necessarily the amount of brain that gives someone a higher IQ, rather the connections they have between cells within the brain and many other factors of such nature. Perhaps with greater knowledge of how our brains work we can overcome some of those limitations as well and increase overall IQs. At this point it is clear that just the brain size does not mean greater IQ, though greater brain sized people may have on average a slightly greater IQ. There is only a very slight chance that given an individual with a bigger brain and one with a smaller brain, the bigger brained person will have a higher IQ. It is likely that there will be no difference measured in their IQs.
Perhaps what the 'smartest' guy might ponder is how one can achieve one's full potential for a happy and satisfying life. Whether this means creating something like a theory or body of knowledge or some other piece of art, or whether this means having a huge social circle and being in constant social contact, or whether this means being a hermit and/or communing with God, or whether this means having children and a family. With this last meaning, one could be happy and satisfied as a parent and nurturer, watching, assisting and supporting the growth or the next 'einstein' or 'newton', the next bank teller, the next shop assistant, the next cleaner, the next doctor, the next 'van gogh', the hopefully not the next patient (of anykind).
Healthy and satisfied with one's lot sounds like a step in the right direction for any person. To this end one could throw in a number of things... compassion, kindness, understanding, patience... and so on. Hope this helps
