Well as a member of gen-z, I'll happily agree with you if that makes you feel like less of a boomer. And I think it mostly has to do with attention. The capacity for focused attention has been deteriorating at a societal level for quite a long time. It's not a generational thing either—we are all facing similar pressures with the sheer amount of information we've been forced to process on a daily basis. That loss of attentional capacity seems to be affecting really important faculties like learning, creativity, and deep work.
I see this in myself all the time but I find a lot of people my age are quite aware of what is happening to us while many older people are stuck blaming the kids—hell, there are times in public when I see older folks more glued to their screen than your average teenager. It's not just young people. The path forward isn't very clear.
