Roughly half probably wouldn’t have been carried out at all, and the remainder would have had problems such as proceeding more slowly, having less collaboration, being of lower quality, or having less (or less likely) practical application.
Environ la moitié des projets n’auraient pas été entrepris et les autres auraient progressé plus lentement, auraient eu moins de collaborateurs, auraient été de moindre qualité ou auraient eu moins d’applications pratiques.
