Acting In Opera

I do not know whether this generation spends enough time on Acting in Opera. I see technique not sufficiently advanced in voice and they can't. Even in my generation, studying with Anthony Addison, Richard Collins, Robert Gay, and Boris Goldocsky, I was not and am not a good singing actor. I know how, but I don't think I have put in the time on the acting. I think Callas was much more involved with the process. I am not know where the generational flaw was at. I do not know why recent generations have given up. I was worried about pitch.
