Today’s manufacturing methods move atoms in great thundering statistical herds

The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an
attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are too
big.

Richard Feynman, 1959

Most interesting structures that are at least substantial local minima on a potential energy surface can probably be made one way or another.

Richard Smalley
Nobel Laureate in Chemistry, 1996
