Just to get things back into proportion, Betelgeuse is one of several hundred pulsating red supergiants visible with the unaided eye, binoculars or a small telescope (here are some around the Double Cluster in Perseus: https://www.dritter.net/astronomy/clusters/ngc869-884_03.aspx https://www.dritter.net/astronomy/clusters/ngc869-884_03.asp...). Many of these are significantly more luminous than Betelgeuse, and it is far more probable (just from the numbers) that one or more of these will turn supernova before Betelgeuse does. The recent fade and subsequent brightening of Betelgeuse are fairly typical behaviour for pulsating red supergiants, and are probably not relevant to whether it is about to turn supernova or not.
