The conditions necessary for a GRB to be a threat to us are kind of hard to miss: namely the death of a massive star, the collision of two neutron stars, or the collision of a black hole and neutron star; that is within ten thousand light years of us; with the pole pointin right at us. IIRC, there’s only one candidate for a GRB to be a potential threat to us, that threat is low, and it’s not likely to be a danger to us for a million years in any case.
As for Betelgeuse, at 650 ly away, it’s too far away to be a threat to us.
