Like others I found the headline confusing. I read it as "Researchers are predicting the use of Wikipedia as a vector for the spread of disease". This may mean that:
- Disinformation and ignorance are diseases.
- Memes and computer viruses are diseases.
- Wilipedia contains information that leads to depression.
- Instructions on Wikipedia lead to substance abuse.
- This is getting entertaining, fill in your own reason here.
One of the definitions I found was:
One who makes great sacrifices or suffers much in order to further a belief, cause, or principle.
I am sure that fits. While SpaceShip II is mainly intended for a non-exploration purpose, the program has resulted in some significant advances in rocketry and White Knight II has significant non-tourism use. These pilots have been involved in other space efforts, I remember the one who was injured from the Rotary Rocket test flights. There are lots of safer ways for these folks to make as much money as a test pilot is paid. They do what they do to advance our progress in aeronautics and space.
Martyrs? Who killed them for their beliefs?
Go away, troll. They certainly died while pursuing something intensely important that they were willing to risk their lives for. The fact that you weren't around to pull the trigger makes them no less martyrs.
Sounds like he just watched Prometheus.
