He's comparing back to 2000's, but lenses used to be much much heavier. I have an all-metal Pentax zoom from the 80's that weights over 600g [1]. I believe the U curve he's seeing reflects the process of DSLRs transitioning from being an equipment restricted to professionals, getting popular during the 90's/2000's (pressuring manufacturers to produce cheaper, more lightweight lenses), and finally transitioning back to professional equipment, as cellphones and smaller cameras picked up on image quality.
