SpaceX Starship Flight 15

 Starship Flight 15 launch, ship catch & CNN's first reactions - YouTube

In an unprecedented maneuver, the Starship spacecraft came sweeping down to a pinpoint landing within the arms of SpaceX’s Mechazilla launch tower. 

This marks the first time in the history of rocketry that the upper stage of a rocket has returned home from orbit to a safe, upright landing — potentially paving the way for it to be used again. 

SpaceX attempted to guide the Super Heavy rocket booster back to a pinpoint landing at its South Texas launch tower, called Mechazilla, but the maneuver was ultimately unsuccessful. The company redirected the booster to splash down in the Gulf.

AI: Grok vs Opus 5.5; C vs JAX, SGLang

surprising they didn't use Rust :)

 Elon Just Called a Rival's AI a "Masterpiece" - YouTube @ Brighter with Herbert - YouTube

Competitive Status: Elon Musk recently admitted that xAI's Grok model is currently behind leading competitors, singling out Anthropic's Opus 5.5 as a "masterpiece." However, he expressed confidence that the upcoming Grok 5 could catch up or surpass it within 2 to 3 months.

Architecture Overhaul: xAI completely abandoned JAX and SGLang, rewriting its entire reinforcement learning and inference stack from scratch in C/C++ (with a minimal amount of C++).

Engineering Roots: Musk noted that the new AI training and inference stack draws directly from engineering solutions developed for Starlink, referencing low-level practices like writing custom headers and manually calculating time (including accounting for leap seconds).

Fight for AI control?

The "sudden" fall of Nvidia CEO (and founder) and the biggest AI "boom" salesman
appears to be more than personal misconduct issue, but a proxy for fight for control.

Will AI tech be "centralized" or "decentralized"?

There are a lot of competing interests, and a lot to lose and possibly gain, 
so politics and big business are making and using the turmoil to establish or maintain control.

Complicated and consequential... Can't be just ignored, even if most people can't do much about it...

And some AI-slop fun :)
