It's Time To Rethink Everything

Theo Browne's CascadiaJS 2026 talk arguing that AI is a "new cloud moment" — just as the cloud removed the cost of provisioning servers, agents remove the cost of building, so the sacred rules of software (file systems, codebases, packages, git, deployment) are worth tearing down and rebuilding from first principles.
