Within the next few decades genetic engineering and designer children will be common. Parents will at first choose to alter there babies genes to prevent diseases, cancers, predisposition to evil, violence, murder etc
As the technology and business advances many more designer genes will start being chosen by parents for there children.
Genes that increase intelligence, resist cancers and diseases, sharpen vision & hearing, increase beauty, increase health, lifespan, or even make immortality possible will start to be used.
This technology and business will probably be very expensive and only available to the rich members of our society. This will inevitably result in a split of the species. On one hand you will have the rich genius, immortal super humans lets call them "Homo Evolutus" and on the other hand you will have the poor genetically inferior humans "Homo Sapiens".
Technologies such as nanotechnology and quantum computers may also have a huge effect on us. In the next 50 years most humans will will have access to endless information via electronic link to the brain. A small chip on your scalp linked to your brain will allow instant download of all human knowledge, internet, math, science etc. But again this technology will probably be very expensive so only "Homo Evolutus" will be able to afford it.
