‘ensure that AGI benefits all of humanity’ turned out to be a quaint, bearish statement. whatever AGI was, it was surely in the past or at most present, and its definition overly concerned with economics. “ensure that mankind can coexist with superintelligent machine ecology”

I find it hard to understand why some people are interpreting Micron’s latest LTA signing as the end of the memory price upcycle. Signing an LTA ultimately means that the amount of supply in the market that has not yet been locked up is shrinking. In other words, the later a

Restrained ground testing begun. The speed at which we can identify and fix issues with both the prototype and our processes is just unreal. At least 10x if not 100x faster than how fast I was fixing issues on my own VTOL builds back in pre-agentic dev days.
