Sonnet 4.5 and especially Codex 5.1 have completely changed the way I build software.
> The fact that tools like Replit also include their own hosting environments is definitely neat, but not really what I was getting at as far as deployment. What I had in mind was managing arbitrary cloud platforms, setting up an optimal architecture for your anticipated scale and usage patterns — whether that's a single Hetzner instance with SQLite or horizontally scaled app servers behind an API gateway with Kafka, Valkey, and Spanner or ScyllaDB — and doing all the DevOps to handle that along with things like CI/CD.
I think this is all possible now. But I don't think it'd work first time because there are so many environmental issues (service auth etc) that can go wrong. Maybe it'd be ok if you have it a root AWS account...
