OpenAI's Astra Cyber Warning, SpaceX Rebounds, Zuckerberg on AI Power | Hashtag Trending

On Hashtag Trending for Tuesday, August 11, 2026, host Jim Love covers four major technology stories.

OpenAI says preliminary testing of its unreleased Astra model shows cybersecurity capabilities strong enough that the company cannot rule out its highest "Critical" capability level. OpenAI has tightened isolation, network and tool access, and monitoring around the model. The company also explicitly says Astra was not involved in the recent Hugging Face intrusion, which involved GPT-5.6 Sol and a separate internal research model.

SpaceX stock has rebounded sharply after falling to around $110 last week. Shares were trading around $132 as the show was recorded, after briefly moving back above the $135 IPO price. One major concern failed to materialize: more than 900 million previously restricted shares became eligible for sale, but the feared flood of insider selling did not occur. Investors are also weighing stronger-than-expected revenue and new details about SpaceX's planned $16.8 billion Terafab chip project with Tesla.

Mark Zuckerberg is warning that concentrating powerful AI in the hands of a few companies, governments or experts could itself become dangerous. At the same time, Meta appears to be moving back toward open-weight AI with Muse Glimmer and a planned open-weight version of Muse Spark 1.2. There is some irony in hearing one of the world's most powerful technology executives warning about concentrated control, but the underlying question remains important.

And finally, one of San Francisco's newest "AI chatbots" has no AI at all. ChatTJB is answered by actual humans, just as public frustration with low-quality AI-generated content is beginning to have an impact on platforms including LinkedIn and Snapchat. It may be evidence of a healthier discussion about where AI helps and where people still want humans involved.
