If you do enough research you can find as many or more "experts" that treat there bee's and although are still have many problems they are at least not starting over every year. I agree that if everyone would quit treating that the bee's would mostly die but the ones that don't would be the true "survivors" but unless you have alot of money, great patients and a bunch of time on your hands this is not a reality. I'm 53 and dont expect to see true survivors in my lifetime
CDD has shown us that many of those who lost 70% of their stock were treating. What i see around is: you treat, you dont treat, loss is quite the same.
As far as seeing survivors, i am very optimistic. Let's remember that when England saw tracheal mites arrive in their land, they had no treatment available and in about 10 yrs (with big losses, true) the bees left were the resistant ones. And no treatment needed anymore. In the US, when the mites came, drugs had been developed and became the answer. Now ~25 yrs later, we start to see less talk about tracheal, less need for treating. So even if it takes 25 yrs - hopefully less, bees will become adapted (resistant?) to varroa and all associated problems.
i have a hive going on at least 3 yrs (maybe more, i did not keep good record before that unfortunately). i couldn't believe how clean the bottom board was on my first spring visit compared to others of my hives. Spotless, you could have eaten on the floor - if the bees had let me share their plate !! Gonna have them make some queens for me.
