| 0:00.0 | Arguably the only topic that's more controversial than AI criticism at the moment is really any mention of the Trump administration. |
| 0:10.0 | Well, late last week, both of these topics came together creating a tidal wave of chaos and recrimination. |
| 0:19.2 | Here's what happened if you haven't been following. |
| 0:22.1 | Back in April, Anthropic announced that their new large language model, which they called |
| 0:27.2 | Claude Mythos, was so good at finding bugs and computer clode that it was too dangerous |
