Achieving a research-level understanding of most topics is like climbing a mountain.
Aspiring researchers must struggle to understand vast bodies of work that came before them, to learn techniques, and to gain intuition
Upon reaching the top, the new researcher begins doing novel work, throwing new stones onto the top of the mountain and making it a little taller for whoever comes next.
People expect the climb to be hard
It reflects the tremendous progress and cumulative effort that’s gone into mathematics
The climb is seen as an intellectual pilgrimage, the labor a rite of passage
But the climb could be massively easier
It’s entirely possible to build paths and staircases into these mountains.
That is, really outstanding tutorials, reviews, textbooks, and so on.
