Is the Vinyl Revival well and growing?

No-one knows for how long even the best pressing under optimal conditions can survive. 200 years? 300 years? Whatever you do, any way you try to copy analog, without any digital interference, there is the end. Replicative fading. 

Unless they start recording in analog again, there will be no true and long lasting revival. Most likely vinyl will disappear in a couple of decades. Of course, there will probably always be people who are into it, and tape, and tubes. Just like in other areas. Digital does sound better on vinyl, but it's all BS, nonetheless, computers should be able to overtake in terms of sound quality soon. But they will not overtake good analog.
In any case, talented musicians are more important than all that.
