There’s very good news from the asteroids. It appears that a large fraction of them, including the big ones, are actually very rich in H₂O… - Freeman Dyson

He aquí cómo describía la situación el propio Einstein: Cuando estaba en el séptimo grado en el Luitpold Gymnasium de Múnich, fui convocado por mi tutor, que me expresó el deseo de que yo abandonara el centro. Al decirle yo que no había hecho nada malo, se limitó a contestar: «Su mera presencia hace que la clase me pierda el respeto». Einstein se alegró de poder ayudar al profesor.

The whole point of science is that most of it is uncertain. That's why science is exciting--because we don't know. Science is all about things we don't understand. The public, of course, imagines science is just a set of facts. But it's not. Science is a process of exploring, which is always partial. We explore, and we find out things that we understand. We find out things we thought we understood were wrong. That's how it makes progress. (2014 interview)

The poorer half of humanity needs cheap housing, cheap health care, and cheap education, accessible to everybody, with high quality and high aesthetic standards. The fundamental problem for human society in the next century is the mismatch between the three new waves of technology and the three basic needs of poor people. The gap between technology and needs is wide and growing wider. If technology continues along its present course, ignoring the needs of the poor and showering benefits upon the rich, the poor will sooner or later rebel against the tyranny of technology and turn to irrational and violent remedies. In the future, as in the past, the revolt of the poor is likely to impoverish rich and poor together.
