I think people should be evolving. It could really interfere with that process if scientists started altering people. Also, consider how lazy a lot of people are. If someone wants to increase their strength they should exercise. If they want to control technology they can use their hands.
There needs to be a good reason for bionics and gene therapy. It could be used to help people with disabilities. I am sure the military would want to use it to enhance soldiers and some ordinary people would want to enhance themselves. It should be illegal for people to compete in sports with enhancements and for people to use their upgrades to spy on people. It should also be illegal to have upgrades that make a person dangerous.
I would not consider bionic upgrades for myself but I would consider something that I could wear and take off.
