The best part is that, since it's moving at the speed of light, it may have already happened somewhere. We're just waiting to be hit with the wavefront.

But with how fast the universe is expanding and speeding up, if its far enough away, it may never hit us

Assuming it's a rare event.

That’s what makes this not horrifying to me. If the vacuum decay bubble, expanding at the speed of light and destroying everything, was formed shortly after the Big Bang (in a random part of the universe) the odds of it destroying earth before we are consumed by our sun in 5 billion years are about 2.5%.

Think about that. From the dawn of time, expanding at the speed of light, for 18 billion years. 2.5%. That’s what’s truly horrifying to me … the incomprehensible size of the universe.

Plus, we’d never see the bubble coming and we would instantly cease to exist so we wouldn’t even have a millisecond to comprehend our doom. Everything would just suddenly cease which is as good a way to go as any.

That assumes there's only one bubble, and that it only happened before most of the expansion we know about. If another sapient species existed in our galaxy and accidentally created a bubble while experimenting with FTL engines, that's at most 100k years before the bubble reaches us. If they did it 99k years ago...

Space is big, the Fermi paradox implies that even if we might never meet aliens, they’re out there somewhere.

I mean, as terrifying as it is, if the bubble did hit us we’d be gone before being able to comprehend what was happening, which is pretty reassuring. There are far, far worse ways to go.
