I think the reason why research makes me so uneasy is the huge use of resources to produce no immediately tangible results. It really takes a lot of courage to continue living in this manner and deluding self to thinking that am doing something useful. Wait, it's not delusion; just lack of far sight that I can't see the useful thing in future. But even for a near-sighted person, not sure which profession is considered directly useful. Education? Literature? Charity? Those things are supposed to be built on pure "values and ideals" and are risky to maintain; one wrong step and the public confidence goes awry. Like towards Korean leadership. It seems as though research is still the best way out. Analogous to a scientist knowing art being better than an artist knowing science. Research is not all about "making money" (all about "spending money" is more like it at first glance); and at the same time puts more rational expectations on the humanity (rational expectation in terms of less emotional exploitation).

Anyway...... the best way out is to stop thinking.
