For me it was at 01h5m50s where Hsu says that super rich Silicon valley guys are already using embryo selection for non-fertility reasons.
Wikipedia says that Elon Musk's 5 sons were via IVF. The mother was 32 and 34 at the births, which is awfully young for IVF. Maybe they had fertility problems, but maybe they did embryo selection. Except that they probably couldn't select for anything beyond sex in 2004, but maybe they did IVF to get twins and triplets.
