Interesting. According to the article you linked, What is Betelgeuse? Inside the Strange, Volatile Star,

The only thing that's certain? Betelgeuse will, eventually, go supernova. However, scientists expect this isn't likely to happen for about another 100,000 years, at which point Betelgeuse will become either a neutron star or black hole.

But I also found A Stunning Revelation Could Mean Betelgeuse Is Set to Blow, which says:

Odds are good that, if the model is correct, we could watch Betelgeuse briefly outshine all other stars soon after the middle of the century before it fades from its constellation forever.

Either way, it seems like the YouTube livestream might be a little premature. ;-)

It would be weird to see Orion without his shoulder.
