AI alignment is why I started Kernel in 2015 and Don't Die in 2021. It's obviously the only thing that matters.
Kernel can now one-shot human thought into AI models. The tech and scaling are singular. I personally invested $70 million to build this.
Don't Die is a values

There is hyperventilation about AI right now. Some say the worry is overblown and others are convinced we’re doomed.
Regardless of the rhetoric, there won’t be any slowing down. The monetary, political and security game dynamics guarantee that. It’s a race to get there first and

We had $630,000 of elite Blueprint creatine stolen earlier this year. Thief used a fake ID and drove off with the delivery truck. Some of you put in heroic efforts to help us find the person. We got very close.
A new batch just came off the line. I may embed myself this time. h

@bryan_johnson I think GLP-1s are showing us how truly detrimental being overweight is to every aspect of life

@bryan_johnson It’s funny how they assume this is because people hate on overweight women.
It’s a fact that as people lose weight they become more energetic.
Also, you need to be motivated to lose weight. That can translate to many positive improvements.
Maybe you study

We were surprised yesterday to learn that Kate was being asked to fill her vagina with ultrasound gel.
The MRI was to characterize her endometriosis. A disease where endometrial tissue develops outside the uterus and grows. It's a gnarly and painful disease with serious health

I had to fill my vagina with ultrasound gel yesterday for an MRI...
I had no idea this was a protocol for measuring endometriosis! how cool

@bryan_johnson A lot of apocalypse obsession is just miserable people romanticizing a world ending reset because fixing their own life feels harder.

I don't trust anyone's AI risk assessment. I don't think we know what awaits us.
Given that, I'm choosing to be optimistic, betting an existence more extraordinary than we can imagine sits on the other side and it's worth fighting for.
