Seems kind of extreme to suggest such a drastic scenario. The possibilities are more numerous than either he’s 100% fine or dead (which, btw, you are the one “putting that into the universe). I wouldn’t guess that’s what people were thinking… rather that perhaps he was in ill health, had lost interest or had other projects that were taking priority, perhaps due to practical financial considerations. Thankfully Ernest has posted an update answering this question, and he says while he has been hindered by some health circumstances recently, things are basically on track.
