The researcher has an obligation of result, not scientifically but economically. The result of his researches must quickly find an economic outcome. The researcher is becoming a scientific entrepreneur. This situation is the result of a slow evolution where political, religious, economic and scientific interests take place.

It's with capitalism that this transformation is the most immediate and the better encouraged and accepted by society.
