I can't tell if this is sarcastic so maybe I'm taking the bait here.

Regardless, there is probably a middle ground for the lamps between "widespread use" and "extinction". It's not great that they are inefficient, but they are certainly historical, and the emissions from a few thousand gas lamps are a drop in the bucket for Berlin and the world.

I would argue that the cultural, historical and educational value of the lamps should be given weight against the downsides and preserved to some extent.
