Then, if you can get it substituted into a zygote from an elephant and bring that to term (far from guaranteed, the nucleus could be subtly incompatible), you still have only one individual that will get old and die. A viable breeding population needs many other, different individuals.
It might be possible several or many decades from now. Pray elephants have not themselves been driven to extinction by then. If they have, bringing them back would be both more valuable and responsible, but even harder with nothing to gestate in.

Jurassic Park is not real. Those dinosaurs would be on life support, not vigorously chasing and eating people. Their lungs would not be sufficient in today's relatively thin atmosphere.

Rather surprisingly, I just found that different oxygen fractions do cause different atmospheric pressures, by altering the density of air, but it's a 15% to 25% difference, not 200%. Maybe it's possible to use this to resolve tensions in estimates of how much oxygen there was. See https://www.science.org/doi/10.1126/science.1260670
Like a lot of island species, they are smaller than their continental counterparts and when relocated to the continent, they gain on average about 100 pounds and grow thicker fur.

Humans who live at altitude for any length of time can see their lung capacity increase. Human sub populations that have lived at altitude for generations also have other adaptations, such as thicker blood, more small blood vessels, etc.
That's in the current world for just a couple of species.
As far as I understand reality, dinosaur physiology is not adapted or suitable to current conditions on planet earth, including but probably not limited to the way their lungs work and differences in atmosphere.
This is probably a good time to agree to disagree about the rest of it.
I want to say first article I read claiming this was 20ish years back. No cloned mammoths yet.
You'll know I make it there, if I stop posting here.
If humans go extinct and some alien species works out how to clone us in vitro and put us in a breathable atmosphere, do you think that would be a life worth living? Hard pass for me, I can’t see that being an experience I would want to endure. It’s life Jim but not as we know it.
If governments or the super rich want a cause to spend their super profits on then working on human immorality or curing our current environmental/social ills would be much more moral.
Bias for what is 'cruel' cannot exist without historical context, for Mammoths or even humans for that matter.
Any species (human or otherwise) is a product of its environment. We've seen this time and time again in historical examples such as human sacrifices, fights to the death, torture- all these ideals were cultivated and accepted by the majority at one point or another.
It's important to also recognise that mammoths only became extinct roughly 4000 years ago and that they are the closest ancestor to modern day elephants. Mammoths existed at the same point in time as bison, grizzly bears, and camels. Camels even predate mammoths and co-existed with species like the giant beaver.
In the timeline of evolution 4000 years is an extraordinarily short period. I'd wager that reintroducing mammoths into a suitable environment would go surprisingly smoothly.

This seems like a catch-22. In this example, you would be reborn in a new environment with zero historical knowledge of the human race.
As odd as it seems... Even if you were made to ride around an alien spaceship naked on a unicycle for your foreseeable lifetime, you would still have no context in the slightest for if this would be a life worth living for you, or if it is an experience you would want to endure.
You would be crafting and designing the social norms for your ancestors from scratch.
Have we learned nothing from Jurassic Park?
