>the "Apocalypse"
There is an absolute problem with this term. It usually means that we go from one cycle into the next one (not always a smooth ride obv)
Different entities "see it" differently and how "it will happen".
The problem with the question of "staying here" is always the answer which is usually just an another question.
>Where would you want to go instead of staying here? And if you really want to go there why are you not there yet?
And yes BO is doing the "supertech on earth but cloaked" aspect for a while and it is not impossible but you are supposed to "cultivate" the human body to do it.
>super PC that can be used to directly talk with Astra
It's called your brain. Yes you can even run Doom on that

>being overpowered in an isekai
Isekai protags always have a "rough start" until they find out how the world works and how they can find their way with their skills and experiences. You need to realize that we are in an "Isekai" already. This is not the world we "came from". You just forgot the place you came from and your abilities. The only reason why you are still at disadvantage because you are not aware of the rules or "mechanics" that govern this world.
