This should be seen as a warning of how much time and efforts and money and stability are required to cultivate a discovery that could have never happened.

Spanish researcher from Madrid. Hired by US on a grant. Worked hard and became director of the Oncology department on the NCI on Maryland. Somebody on the Spanish government decided to bet strong on him and recover it for Spanish Cancer research. A specific customised job offer was created for him. Politicians came and go; some are sensitive about science, other not so much. Some promises were never fulfilled, and he was about to quit and migrate again until private companies stepped on the scene with the resources needed and the will to allocate those resources. Money well spent, that was about to never find his target.

Nobel prizes were created exactly for this kind of humble, serious, zero-nonsense, zero-drama, all-work scientists.

The question here is: how much "Barbacids" quit US in the last year? Scientists aren't stupid. Everybody is aware that Barbacid in US today would have being harassed just for speaking Spanish and having a scarred face. All points that US is bleeding talent at a level never seen in their history.
