Everything about this is genocidal. If it were done to any other group anywhere in the world it would be condemned as genocidal. We are being systemically denied a homeland, a people, and a place in history.

the one thing about having a child that has surprised me is the return of the love. my kid really loves me. he really does, he's empathetic and cares about me. if i look stressed, he notices and tries to cheer me up. even when he was younger than a year old

HOW THE XAI GROK 4.20 AGENTS WORK
The four agents in Grok 4.20 (Grok/Captain, Harper, Benjamin, Lucas) form a native, production multi-agent collaboration system that runs on every sufficiently complex query. This is not a user-facing framework you have to orchestrate (like

Since the race swap is never the other way around, this is obviously deliberate White erasure.

Now’s not the time for xAI to touch multi agent systems
Hold off a bit,
Understand model attractor states,
Solve continuous learning,
Do a great job with memory,
Stay under the radar,
short of SOTA
Be comfortable as the clown
for a few years
And you’ll return to win it all

SpaceX is painfully serious about space data centers. They have a cyclotron to test their flight hardware. It’s not only data center hardware that benefits from this ramp up in testing cadence. But it’s not a huge leap to assume that there will be some data center chips headed
Christian Keil@pronounced_kyle· Feb 17, 2026If you want data centers in space, you need radiation-tolerant chips.
Specifically, chips that survive both:

▸ bit-flipping, energetic particle strikes (SEE)
The latter is scariest. Google tested its Trillium chips and found that the

Grok 4.2 will be about an order of magnitude smarter and faster than Grok 4 when the public beta concludes next month.
Still many bug fixes and improvements landing every day. The public beta gives us more critical feedback to address.
Aaron Burnett@aaronburnett· Feb 17, 2026we're already using Grok 4.20 (agents) in our research process, from a research perspective it does feel like we jumped another 9.

ruing technical terms here. Mixture of Experts (MoE) has literally nothing to do with what xAI actually shipped in 4.20.

It’s worth pointing out that ChatGPT 5.2 performed significantly worse on this test, as shown in the first image.
The second image shows Opus 4.6.
The third image shows Gemini Pro.
The fourth image shows Grok 4.2.

Grok is most physically accurate of the four.
Opus rear bike frame makes no sense structurally, there is no connection from pedals to rear wheel, both legs of Pelican are on the right side of the bike and handle bars are disconnected.
