Humans have proven to be incapable of making real progress in science given the effort. Especially academia. We haven't cured many diseases and cancer when we should have (and no im not an amateur and yes I do believe we can "cure cancer". Debate me).
We already have a trillionaire, whats the difference? The only difference I see is that people who were previously rich, but considered themselves middle class, are now realizing they are actually poor just like the several billion humans around the worldanyway.
What a miserable, misanthropic take
Let me illustrate why you are wrong:
800-400k years ago: humans intentionally create and control fire
300k years ago: humans become anatomically modern
~ now: all of astronomy, biology, medicine, vaccines, spaceflight, antibiotics, sanitization/sterilization, physics, chemistry, fission and fusion, electromagnetism.........
I think we're on a decent pace if we can manage to not exterminate our species.
Many cancers are "cured" in the sense that they're detectable and treatable. My grandmother lived 35 years longer than she would have by detecting breast cancer early and getting a mastectomy.
There is currently a $800 SOTA blood test that can detect most cancers before any symptoms. Maybe a decade until it's a routine part of your annual blood test?
