I joined xAI to manifest AI’s acceleration of scientific discovery.
With the release of Grok 4, I now feel we have the foundation upon which we can Understand the Universe.
The techniques that brought you Grok 4 will compound the next scaling paradigms, and humanity’s scientific and artistic endeavors will feel the inexorable leverage of AI.
To my friends and colleagues at xAI, it is the professional honor of a lifetime to work alongside you - I am ever grateful for your tenacity, mentorship, and brilliance. Not a day has gone by that I haven’t pushed my limits, solved interesting problems, and laughed my head off :) Time dilation here is real; I live lifetimes every day.
To everyone on X, this revolution is still in its infancy, and Grok 4 is the edge of the event horizon.
If you want to chart a path into the unknown, etch your name in the stars, and charge into the singularity, join us.
Ad astra, per aspera!
Elon Musk: Even if civilization has just a 1% chance of being annihilated, we should back up the biosphere on another planet.
“Sometimes people are puzzled as to why we're doing it. The reason we're doing it is to make life, consciousness, multiplanetary. So as to preserve the future of civilization and consciousness and life as we know it.
There's always some chance of something going wrong on Earth. Overall, I'm like fairly optimistic about Earth. Let's just say there's a 1% chance, for argument's sake of life as we know it and consciousness being annihilated on Earth. I think it's still, even if there's just a 1% chance of civilizational annihilation, you'd want to protect against that by having a second planet back up the biosphere effectively and ensure the continuity of life and consciousness.
This is the first time in the 4.5-billion-year history of Earth that it's been possible to do so. So we should take advantage of this window while it is still open. And you know, we don't want to be complacent and assume that there will be this constant upward trajectory of civilization. Hopefully that happens, but it might not. And so this is about protecting the future of life itself.”
