The laptop was never the interesting part of coding agents.

It was just the first convenient runtime.

Your laptop has the repository, the shell, the secrets, the package cache, the local database, the half-working dev server, and whatever credentials you forgot were still loaded in the background. So the early version of agentic coding naturally ran there. It was close to the work. It had all the messy context. It was also a very strange place to run something that might edit code for an hour while calling tools, installing dependencies, and touching private systems.

AWS published a Bedrock AgentCore post this month with a very good hook: you should be able to close your laptop while the coding agent keeps working.

That is the demo-friendly version.
