There was a time which people thought the hyper realistic photographs actually capture the soul of an individual. There was a time medicine considered sinful and refusing to see a doctor elevated a person to sainthood. I'm not kidding: http://www.badnewsaboutchristianity.com/gg0_medicine.htm

Illness was indisputably caused by sin. The Bible said so, and so did Church Councils. The only alternative explanations given credence were diabolical possession, witchcraft and other satanic machinations. In Christendom, from AD 300 to around 1700 all serious mental conditions were understood as symptoms of demonic possession. Since illness was thought to be caused by supernatural agents, cures had to be essentially supernatural as well. Every cure was literally miraculous, and these miracles could be effected only by prayer, penance and the assistance of saints. To claim otherwise was heretical and blasphemous.

The Christian ideal was that women should die rather than allow themselves to be helped by a physician. Some women won their sainthood for doing no more than declining medical assistance. In the fourth century Saint Gorgonia, the daughter of two saints, was trampled by a team of mules, causing multiple broken bones and crushed internal organs. She would not see a doctor, as she thought it indecent. According to Christian sources this modesty miraculously cured her, and a second such self-healing miracle assured her sainthood. Today, Gorgonia is a patron saint for people afflicted by bodily ills. We do not know how many thousands of other women with identically modest Christian scruples died following her example and are now forgotten.

By the Middle Ages, medicine had regressed on all fronts in Christian lands. Muslims who came into contact with Christians, as Usama of Shaizar did during the Crusades, were shocked by the crudity of their medicine — and it was not only medicine, but public health too. Whereas Muslims adopted public baths (hammams) and insisted on washing before meals, Christians adopted the view that it was wrong to wash. It was flying in the face of God to presume to clean off his honest Christian filth. Christians were obliged to accept the will of God and the disease and misery that went with it. Queen Elizabeth I was famously said to have bathed twice a year, whether she needed to or not.

We may laugh at these things now. But what would the future generations think of what we'd be thinking now. I don't want to be laughed at and honestly I'm a huge fan of Deus Ex (The original was far ahead its time) Ghost in the Shell, Altered Carbon and cyberpunk in general.

Safety is Key

Therefor I'd like wearable upgrades which I can put on and take off. Te biggest advantage is that I can switch what I'm going for. I can pick and choose different abilities.
