Uh, you have a whole lot to learn about cognitive science overall if you think we only use 2-5% of the human brain, or that it can't be surpassed.
The human brain is a REALLY POWERFUL computer, but it can be surpassed... and will be. I expect humans will lose the stigma associated with cybernetic enhancements and simply use implants to upgrade our own intelligence in response to the rise of AI intelligence.
Yes, its possible to create human-level AI w/o emotions. But emotions are already used in AI, particularly in some of the more advanced strategy games. It's little more than a state machine whose outputs are given as inputs to the logic processing algorithms. So a pissed off AI would be more likely to attack an opponent, even if doing so wouldn't be the optimal choice.
As for the human brain, the concept that we use less than 10% of it is a myth, and has been disproven decades ago. Functional MRIs clearly demonstrate that we use roughly 30-40% of it at any given time, and which 30-40% varies based on which task we're doing. Ultimately, all or nearly all of the brain is used at one point or another during our lives. We don't have a massive reserve of unused brain power that's just waiting to be unleashed.
But there's a lot of money to be made by charlatans who keep this myth alive. From pills that claim to tap the immense reserve to New Age gurus who claim to be able to do the same thing if you buy their CDs & listen to them at night... millions of people are led to believe this bogus claim and they turn around and spend an obscene amount of money on worthless products as a result.
I could go on & on, but this is likely already tl;dr for most people on FAF so I'll just stop here.*lol* Unless you're going to build a female robot dragon, I somehow doubt Telnac would be interested.
Actually about the brain blabber talk I heard from somebody else and just copypasta it.
AI with emotions in strategy and RPG games does not exist, they are computed to act according to your DIRECT actions, like killing a set number of enemies or picking an answer.
The time which the brain is at the peak of it's activeness is when you are 18 years old, then it slowly degrades. Though, 100% will never be used of the mind, as still youngsters with so many percents still are affected by the society and get killed in horrible car accidents so easily. Would you stay forever young, like that?
I am sure the peak is about 40% - 50%, and people with higher IQ are able to use more parts of it. Though, different parts are used for each person - that's why some people are outrageously smart and some are amazingly artistic or talented.
AI will never reach the complex of a human, the human brain is the only one that will ever be proven to have feelings. Robots are only an aid.
Maybe they can surpass the knowledge, but not the intelligence. Humans learn quicker, humans surpass emotion and love. The human brain is so advanced that nobody could understand how it works accurately.
The other mass of unused brain does exists, and it's called talents and skills. Maybe not skills, because they are aquired. Brain is a hard drive of windows, with many more actions and folders, though, some folders are compressed and you must undergo challenges to decompress them.
Fun stuff. I would never replace a human with a robot, but if a robot would look exactly like a human, work like a human and have minor emotions for an affordable price, I will research.
Cybernetics are only an addon. I fear that I will die the last person in the world with 100% humanity. No animals and no robots - all rejected. I like this era the most, why change it so fast? Why do I like it, it's peak.
