Big brain tech dude got yet another clueless take over at HackerNews etc? Here's the place to vent. Orange site, VC foolishness, all welcome.

This is not debate club. Unless it’s amusing debate.

This exploit was discovered by two security guys at the Brave web browser.

I have yet to see any roving Brave infosec mall ninjas react to the fact that they plan to do this agentic AI shit too:

Brave gets credit for finding this exploit in Comet, so well done! But how did they find it? Well, Brave is trying to do its own AI agent web browser. Even though this is a fundamentally stupid idea that cannot be secured.
