Plus on est à un stade éloigné de la mise en marché, en termes de temps surtout, plus il est difficile pour l'industrie d'investir, parce que, suivant leurs modèles, le rendement est actualisé, et plus l'échéance est longue, moins le rendement est bon dans leur esprit.
The further you are away from the markets, especially from a time point of view, the more difficult it becomes for industry to invest, because their models discount the returns that they get, and the longer the time, the less the return in their mind. So you have to deal with it, and that's why you have a progressive kind of a model.
