Now this means that the newest teaching on the Dead Sea Scrolls totally destroys the past view that a bunch of Essenes lived there and we're busy working on scrolls in the buildings near there.

At this time there is little support for the idea that the Essenes lived around where the Dead Sea Scrolls were found.

Now it is likely true that many books and websites are now out of date too.
My guess is that many people are still stuck with using out of date research and do not yet know what the best views of science teach us today.
