Use facts or examples and the concepts of genetic drift

Humans are adapting to the enviroment by creating aids/tools; we are actually on the verge of being able to select desired traits by using genetic engineering, in-vitro fertilization, and other molecular biology tools. For example, we can now detect and correct some genetic diseases and we also have the tools to select the sex of a baby and/or some of the baby’s physical characteristics. No longer does an individual have to have a decent diet to survive, reproduce, or age because there are drugs that have been developed to correct these things. What effect will this have on human evolution? Use facts/examples and the concepts of genetic drift, gene pool, adaption, selection, genetic flow, etc to explain answer.
