Ted Underwood: (just, say, hypothetically?) There's also internal incoherence in making the first part of this all about moralized great-power competition and then saying that safety testing (incl for alignment r…

jeremy.lewi.us: I think MCP is the wrong approach to solving the safety problem. The solutions is code mode with code running in a proper sandbox . The JS sandbox in browsers is an example. Then you can define a v…
jeremy.lewi.us: CORS is an example of what I think this should look. AI is so good at writing code these days I don't think rewriting code to be compatible with a sandbox is a huge barrier
