And while you may have some substance behind your claim that the majority of population don't have enough brains (though this is debatable), the technology may be specifically intended to address this issue. In fact, even simple calculators do exactly that, though on a rather primitive level, of course
After all, any technology hinges on making human life better and easier in some way or other
Transhumanism? I havent considered that possibility.
Although I am not sure people will like this idea, that is by definition the extinction of humanity as we know it now and being replaced by cyborg, half sentient robots.
We dont even know if robots can have consciousness, so I am not sure humans would welcome the idea of being "augumented", we have no idea what that experience will be like and we are familiar with what we know already.
