That’s kind of misanthropic, talking in absolute terms. I could agree in terms of low possibilities but certainly not absolutes. I feel it does a disservice to the few who actually come up with genius solutions to problems humanity faces and the many who dedicate their lives to solving them too.
Is it, really?
With current progress I don't see humanity surviving even another 500 yrs, honestly.
The main intelligent race at that point is likely going to be something like a symbiont/cyborg that's part machine. At least nothing it'd consider human.
Millions of years is a long period of time. Humanity has only existed for roughly 200-300k. That's less then 1% of the projected time period here.
