Intelligence, in real life, is quite a nebulous thing. We can perhaps measure an IQ number, observe that someone is "bright", or remark upon their achievements, but while all these things are "correlated", it is a loose correlation with many exceptions. I am not convinced that producing people with high IQ's and declaring them "intelligent super-humans" will result in anything dramatic, unless that is followed up with a lifetime of enrichment: superb education, good parenting, and formative life-experiences. I do volunteer work in an adult literacy program and, learning disabilities aside, some of these folks are truly very intelligent and fully capable but have been set-back in childhood and young adulthood because of circumstances beyond their control and utterly unrelated to genetics. If we really want to create super-intelligent beings, there's a "low tech" way to do that will be far more effective than genetic engineering: treat education as a mission-critical priority and make sure kids are taken care of.
