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?

They have about as long as they work for because you are not going to see but a few true class a designs anyway, count yourself lucky that you have your sugden because class a will soon be a thing of the past.

Not long in general but if you have one and love it nobody will make you get rid of it. Also there will always be things sold as long as there are people who want to buy. But not many want to so expect to pay a premium for an increasingly niche item.

Greta has never pretended to be anything but a kid.  Her consistent message is to listen to the scientists.  Stupid science.

Linear powered class D module with a low power, class A input preamp section is the future.  High powered Class A output is like using a V8.  Inefficient and wasteful.

It’ll be around. Fear not.

Tubes are still in use, vinyl is till being played, class A will be around.

As far as the environment goes, wonder what is dirtier to make. A gallium nitrate chip, or a class A chip.

And what’s with these “men” tailing aim at a young girl?

Threaten easily, do we?
