The Sentry intercepts the untrusted code’s syscalls and handles them in user-space. It reimplements around 200 Linux syscalls in Go, which is enough to run most applications. When the Sentry actually needs to interact with the host to read a file, it makes its own highly restricted set of roughly 70 host syscalls. This is not just a smaller filter on the same surface; it is a completely different surface. The failure mode changes significantly. An attacker must first find a bug in gVisor’s Go implementation of a syscall to compromise the Sentry process, and then find a way to escape from the Sentry to the host using only those limited host syscalls.

智能体是能做事的A I。LLM是近几年AI领域最重要的发展。已经在语言理解与生成、对话交互以及知识整合等方面展示出超凡能力，但它是“缸中大脑”——擅长思考、分析与回答问题，却并不能真正地做事情。而在真实世界，大多数认知活动并不止于“给出答案”，而是要有完整的“认知-行动”闭环：我们要求AI得能够自主的拆解复杂需求，规划流程，调用工具和资源，实现从感知到决策再到执行的完整循环；进一步我们还希望AI的行动能够超出计算机和互联网领域，在物理世界中为我们做事情，则需要AI能够感知物理世界的信号，进行匹配具身的思考，通过设备/机器人把决策转化为执行，对现实环境产生直接影响。
同样的情况也发生在我自己身上，我本身就是一个中年程序员大叔，体力和精力比以前弱很多。
