Quite. It is a variable star, and we don't know if (or even expect, really) obvious changes in its brightness would correspond to changes in its core fusion processes. I liken it to all the buzz that happens in the media whenever Yellowstone hiccups. It has probably had hiccups since before modern humans came around, and we don't know what it does right before it goes off, or even if it does anything noticeable at all.
But it is neat that such a prominent star in the sky is now much dimmer than we've been used to. The stars aren't constant.
Added: Good news though is that, unlike Yellowstone, when Betelgeuse finally does blow up it will be spectacular and not dangerous. At least to us.
Let's all place bets- what will explode first- Betelgeuse or Eta Carinae? I predict that we will all either be 6 ft under by then or we will all reside in immortal artificial bodies by then!
