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?

@bpoletti  Be nice... this is an audio forum, no need for politics.

@mrmeaner  Perhaps a better question would be, how long does Class D have?

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.
