Sorry that it wasn't clear in my talk (and I agree that it wasn't).
Using a lockfree library isn't a last resort.  Doing your own lockfree
code is the part that should be a last resort.

I still wouldn't replace a locked std:: data structure with a lockfree
one without measuring performance, but if you see that it improves
performance, then go for it.
