I don't know if this is an unpopular opinion or not, but I hate the anthropocentric mindset that humans are immune to extinction and that you can't wipe us out without wiping out all other life on Earth. It's entirely possible we are, but we don't know for certain.

It also comes across as very anti-environmentalist. A big way to convince people to save the environment is to convince them that we'll be negatively affected if the rest of Earth's life goes, right? Because if you tell them that humans will be fine no matter what, you're basically telling them it's okay to continue driving species to extinction with constant pollution and climate change since it won't affect humanity, even if that's not your intent.

Plus, anyone who keeps up with politics and social media nowadays knows that human society is regressing. This is the same species that elected Donald Trump as president, did a terrible job at handling a worldwide pandemic, sees homosexuality as a disease, and thinks only the rich deserve basic healthcare.

I believe that if humans DO go extinct, it'll be due to the same thing that's currently harming other species AND humanity right now: capitalism. The only remaining humans a few million years from now will be rich billionaires who can afford basic living conditions, but they'll eventually go as well. (At least, that's what happens in MY future evolution project.)
