AI is to a certain degree a different story, but also there it depends what you're doing.
We live in a thin atmospheric skin around the planet, and that skin has a finite volume. If earth was the size of an apple, the atmosphere is thinner than the Apple's skin in proportion.
Pretending we can do whatever we like for infinitly long inside an finite volume is completely unhinged. The financial and political elites, who some frame as the true geniuses point to technological solutions that are always "just around the corner" for the past decades with some of them even eying to leave the planet behind entirely.
All of that while we know how to address the issue.
