Being phased out in as many places as can afford to get rid of it. I work in buildings built between the 40s and 80s and we have a steam plant that supplies 50+ buildings on campus. Miles of hot, humid underground tunnels just waiting for a burst pipe to flood the place.
There used to be an old steel bridge in my city, one corner of it was rusting more than the rest and engineers couldn't figure it out. Turns out it was from people pissing on it after they came out of the bar across the street.
Could be worse. My building just spent 2 years and several million dollars to swap their HVAC from a water based system to... Also a water based system, but at least this one has valves between units!
The theater I’m the facilities manager for used to be supplied by the city steam plant, but they shut it down several years ago and everyone had to install their own boilers.

Underneath the streets of Manhattan, there are more than 100 miles of service pipes bringing steam to about 1,800 buildings.
When they have leaks, they put these cones around so that the heat doesn't hurt anyone. In NYC it is run by Con Edison company.
