We could see that supernova happening (our kids will)

Betelgeuse should go supernova in the next decades, not millennia... but decades.

Betelgeuse is not anymore fusing hydrogen into helium, but carbon into neon/magnesium and Betelgeuse is not massive enough to fuse neon and magnesium into silicon and there is not much carbon left, thus Betelgeuse should go supernova from the next decade to few more decades
Please Betelgeuse don't wait too long

To quote the Wikipedia article:

Quote:Astronomy magazine described it as a "bizarre dimming" and popular speculation inferred that this might indicate an imminent supernova.This dropped Betelgeuse from one of the top 10 brightest stars in the sky to outside the top 20, noticeably dimmer than its near neighbor Aldebaran. Mainstream media reports discussed speculation that Betelgeuse might be about to explode as a supernova, but astronomers note that the supernova is expected to occur within approximately the next 100,000 years and is thus unlikely to be imminent.

yes, on wikipedia that was 2 or 3 years ago
On the video that's a recent publication (although not peer reviewed, yet) from june 2023
