Earth will become uninhabitable way before the sun explodes.
Last estimate I read was like 500 million years before the sun gets hot enough to start negatively effecting the water cycle, and then it just gets dryer and more inhospitable from there.
Of course, we’re artificially making things hotter way faster than that, so probably a few hundred years before large mammals have a hard time maintaining homeostasis due to the temperature.
Maybe we’ll get dinosaurs 2.0 and they’ll have enough time to get smart enough to realize we used all of the cheap energy and doomed them to die on a hot, barren rock.
