The above video created by explains some recent advances in genetic engineering and some of the possible consequences.
The video focuses on the discovery of CRISPR which allows genetic engineering to be done much more easily and at a lower price.
If you're interested here's an article about CRISPR from a year ago in the New York Times
Questions to bring up:
If the price of genetic engineering goes down dramatically, in theory, the quantity demanded of genetic engineering should increase and as the quantity goes up it may become more acceptable in society which would increase demand making the quantity demanded go up further. Is this accurate? Are there other things to consider?
The narrator says that banning genetic engineering would have negative consequences since it would then be up to the black market to do with it what it will. Is regulation a good idea and how much if so?
What might be some of the externalities or secondary effects of more genetic engineering in our society?
If humans were to greatly increase their lifespan, would that be a negative externality on humans who are born in the future since population (and resource consumption) would increase even faster than it does currently?
