My opinion:
Having a IQ that high changes nothing. At least nothing that I know of. Being that much of a genius causes you nothing but grief if you want it in order to make it a useful thing in social interaction. They condemn what they do not understand. Believe it or not, being 0,0000...1% is a hardship that will, without the sheer determination, the just right ignorance and an extremely steady and strong character, leave you very much alone, a target of ridicule and you'll be too otherworldly to interact without making you and everyone around you miserable.
And just having a high IQ alone will not make anyone excel at anything, not even academics or the ability to solve problems. Sooo, no, I find it hardship enough that people expect of me to be as good as all these other gifted people just based on tests. Because I'm not all that.
I do think genius are made - being born with in the range of 99%+ will give you no gift in life for free. You'll all have to achieve it after your birth. You may indeed be offered more opportunity with 99%+ but seeing how few opportunities men actually makes true in a the great sea of them he right in... it being there, doesn't mean you will notice it being there.
Great IQ doesn't make you life-smart. You can be the very best and most life-smartest person ever and score a 70 (or lower!) on a lousy IQ test. Imo we have people like that on WP, gladly.
Really, that 'life-smart'-thing doesn't have anything to do with IQ. It's more along the lines of satisfaction, happiness, joy and being content with what the opportunities one has discovered already or is still in search of.
