Although the Human Brain Project has many supporters, it also has to cope with numerous critics. Many do not believe that it is possible just yet to build a specific simulation of the human brain because neuroscience is actually still at its launch. The coordinator of the HBP mentioned in 2009 that he plans establishing his ideas within 10 years. This time frame seems to be overwhelmingly optimistic for many people. Moreover, some argue that in stating this, it aids them to receive more funding. In addition, there are many people who are unsure about an emulated brain's value as it will not perform any cognitive functions.
Opposed to that it is also often argued by scientists that, even if simulating a single cortical column of a rat is a result nowhere near a human brain, it is still a significant start. Knowledge about the brain's functions is growing exponentially and at some point, although maybe not in ten years, the success of a simulation will become a powerful tool. Many believe that most likely, the first model will be a failure. However, any resulting failure in this model will bring neuroscientists closer to a better model.
With great Innovation comes great responsibility.
Bringing new technologies, such as artificial brains or new scanning devices for the nervous system, into our world naturally creates certain risks. There is always the possibility of abuse of knowledge, be it deliberately or involuntarily. There are a great number of other ethical questions, such as: it is ethically acceptable to treat patients with cognitive problems. But is it also acceptable to enhance cognition in healthy people to make them smarter?
With great innovation come great ontological questions.
- How does the mind work?
- Where does our mind come from?
- What is consciousness?
- Is there a relationship between the mind and our biological brain?
