Is Richard Feynman's Lecture on Quantum Physics Still Relevant Today?

Hi all. My first post. I hope I posted in the right section.

I watched ep 1 of these old videos lecture by Richard Feynman and wondering if it's still valid. Or should I take on his ideas and formula my own understand from all possible views. Or how should I learn this subject.

Because as a rookie trying to grasp quantum physics, he states light is a particle when at high school we are still taught light is a wave. :S.

Well, quantum mechanics ties the particle-wave duality of photons, which have both wave-like and particle-like qualities. First year chem in university will teach you quantum physics, and I'm sure senior high school courses touch on it.
 
Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
