The scariest part of this is that Anthropic showed some restraint in not releasing a potentially dangerous technology but some of their competitors (such as OpenAI and xAI) might well not. Whether Mythos is as scary as it sounds or not, the reality is that without government regulation on releases, we are well and truly fucked. Jim VandeHei (@JimVandeHei) This is the scary phase of AI — a model deemed so powerful that its full release into the wild could unleash untold catastrophe. 🚨Based on our conversations with government and private-sector officials briefed on Mythos, this isn't hyperbole. It's reality. axios.com/2026/04/08/anthrop… — https://nitter.net/JimVandeHei/status/2041817666881503351#m

LLMs Cannot Learn Temporal Reasoning Due Architectural Limitations
By
–
To anyone who read Rebooting AI back in (checks notes) 2019, this is both hilarious and unsuprising.

Domain-Specific AI Versus General-Purpose Chatbots Debate
By

perhaps we should compare calculators to humans? also, if you actually follow my work (eg October 2025 NYT oped) you will know I am a fan of domain specific AI (like Waymo) and skeptical of domain-general AI (like chatbots), so I appreciate your making my case for me.
