Back in the day every manufacturer's top of the line offerings had some type of metal lens barrel, but now everyone makes them out plastic.

Now plastic often out performs metal in many ways.

I'm not sure it does. The trouble with polymers are they're susceptible to UV damage, which, over time, cause them to become brittle. So far as I can tell, this issue hasn't been solved.

Well, let us know when you start breaking them. I've never heard of lens barrels breaking, although I have heard of Sony metal lenses breaking in two at a joint.

This is due to poor engineering choices, rather than chosen materials. You know this (or perhaps you don't).

Like I said, let us know when you start breaking lens barrels.
