What a dystopian world view. Even if AGI comes to fruition, which is not certain, that does not invalidate humanity's significance.
I'd bet my life savings against $100 that we will not have strong AI with "cosmologically significant powers" that makes "everything that came before it...seem insignificant" in less than 12 months. I'd give 10:1 on two years, and 2:1 on five years.
OTOH, there were thousands of generations where very little changed in an average human lifetime. People's worldviews are far more instinctual than most care to admit, and "steady-state" instincts would have been selected for.
