Is a secure AI assistant possible?

OpenClaw is a tool that lets users create AI personal assistants by connecting large language models (LLMs, or AI systems trained on huge amounts of text) to external tools like email and file systems, but this creates serious security risks. When AI assistants have access to sensitive data and the ability to take actions in the real world, mistakes by the AI or attacks by hackers could expose private information or cause damage. The biggest concern is prompt injection (tricking an AI by hiding malicious instructions in text or images it reads), which could let attackers hijack the assistant and steal the user's data.
