Science is facing a fundamental turning point of its history. Never as in this historical moment it appears giant and powerful, but at the same time it shows high fragility: the concentration of information control power in the hands of few commercial groups, the iniquity of a system that benefits developed countries, the restriction of academic autonomy by political and economic power, the precariousness of working conditions of young researchers, the increase in the number of cases of scientific fraud and misconduct, the questioning of its authority by a portion of the public. Can openness be understood as a system capable of strengthening science and treating the diseases that afflict it? The essay is aimed at answering this question.
