This is still orders of magnitude longer than our distance to the Roman Empire. We've gone from no flight to space travel in 150 years and you're worried about 50 million years.
The US life expectancy dropped one of the largest drops ever (1.5 years) and instead of facing the actual real-life disasters happening, "science enthusiasts" are quoting TV shows about science fiction disasters that might happen in 50000000 years... while the scene outside the window literally looks like this: https://abc7news.com/why-is-the-sky-orange-sf-yellow-califor...
Do we really have 50 million years? Very unlikely. Do we even have 150 years? I'd take odds against, we've just come way too close to all-out nuclear war recently and international relations are not trending in a promising direction.
