iacisrmma,
There is a shift taking place in which transmission is being passed from parents to Roshei Yeshiva
As long as there is some form of mesora based on roshei yeshiva who are presumably talmidei chachamim , I think yidishekiet will survive (though I agree I dont like it either).
It is people deciding on their own based on their own research that I think is dangerous. And can and has led to serious breaches.
Read Haim Soloveitchiks’ excellent “Rupture and reconstruction” for a fantastic piece on the shift taking (that has taken?) place
