In this talk, we would argue that we need to apply kinetic theory analysis to examine
the relevance of various Alfven eigenmodes (AEs) in burning tokamak plasmas. This is because
various AEs have different coupling strengths to the energetic particle drive. We would also
suggest that we may have sufficiently reliable expressions for AE-induced transport coefficients.
The major intellectual challenge, we submit, is, thus, the nonlinear saturation processes of AEs;
such as toroidal Alfven eigenmode (TAE) and beta-induced Alfven eigenmode (BAE). We, thus,
need to focus on developing necessary physics insights along with analytical/simulation tools.
