We just can't trust dependencies and dev setups. I wanted to say "anymore" but we never could. Dev containers were never good enough, too clumsy and too little isolation. We need to start working in full sandboxes with defence in depth that have real guardrails and UIs like vm isolation + container primitives and allow lists, egress filters, seccomp, gvisor and more but with much better usability. Its the same requirements we have for agent runtimes, lets use this momentum to make our dev environments safer! In such an environment the container would crash, we see the violations, delete it and dont' have to worry about it. We should treat this as an everyday possibility not as an isolated security incident.

This is the security shortcuts of the past 50 years coming back to bite us. Software has historically been a world where we all just trust each other. I think that’s coming to an end very soon.
We need sandboxing for sure, but it’s much bigger than that. Entire security models need to be rethought.
