How long does Class A have?

Hi Guys/Gals
 I have a Sugden A21SE which is a Pure Class A single ended design, I absolutely love this musical amplifier with its strangely plentiful 30wpc, it runs hots as they do, I always enjoy watching the faces of my uninitiated friends when they touch it after I mention they get hot, lol.
But in this modern green era I wonder just how long do Class A amplifiers have before Greta Thunberg gets wind of this inefficient method of creating sound and pisses on the parade?

Thoughts?

Class A is still very popular Pass labs 1st watt is very popular 
as well as their integrated 60  very good products if you have efficient speakers ,still a very solid choice.

And with Thorium on the horizon, class A will cease to be a concern…

Totally agree about Pass gear...and amazingly sound like "music" despite not containing a single tube.

A will be around until no one exists to prefer it over what is still possible.

Class A is a niche market. It's bought like jewelry because people want it. It will probably last forever.

I noticed the lead question mentioned a single ended class A amp. ALL single ended amps are classe  A. They have to be, the circuit is inherently class A. So if single ended amps last, so will class A.
