I think renaissance man, an ideal worth striving for. This is because human mind, and brain itself can create immerse amount of value in short time if it’s provided with right kind of cues.
Still it’s rather unlikely possibility to achieve to know everything about everything worth knowing. With cybernetics this might again be possible in time, but know we must carefully settle with all that we deem worth knowing. It is limited amount that we can know.
Despite the limitation, it is worthy effort to be driven by curiosity and live the life of philosophy. If we do this, and meet other people who do this each of us have our own strengths and knowledge. It is through other people that we can access to their knowledge as well.
Combined power of networks is incredible because of the speed.
Brain is technology that does not get old.
