It's a religion at this point. The problems facing humanity on Earth appear daunting, so it's easier psychologically to put faith in sci-fi ideas that might be impossible, but are simple by comparison to thinking through concrete solutions to our woes. Humanity sits atop a food chain that is going extinct, right before our eyes, and it's long past time to stop hiding from it. Human life on Mars is neither feasible nor imminent. We aren't getting level 5 autonomous vehicles or AGI or androids or flying cars or time travel any time soon either. These are ideas we run to when facing the absurdity of our existence becomes too much to bear.
