This note is a short appraisal of the status of nonlinear theories for drift waves and trapped particle instabilities as seen by the author. Such instabilities are thought to play a crucial role in the energy confinement capability of tokamaks. Some of the phenomenological and strong turbulence theories are discussed followed by a discussion of the more quantitative weak turbulence theories.
