Not only do you need to have time travellers, you need to have time travellers who are interested in reviving you. The farther in the future you get the less the chance that any time travellers would want to revive you (although they might always want someone for historical interest so the chance might never go down to zero.) The more advanced the technology required, the longer it’ll be and the less the chance they’ll want to bother.
Like I said, I guess this comes down to how you imagine such a future looking beyond “has time travel”. I tend to assume some sort of post-scarcity omnibenevolent utopia, myself …
There’s also the possibility that some technology simply will not be developed. Perhaps there are some fundamental quantum limits that prevent getting an accurate remote scan of you. Perhaps civilization has a 50% chance of dying out before they invent the magical technology.
Before they invent any magical technology, you mean. There’s more than one conceivable approach to such a last-second rescue.
