Real productivity boost with @claudeai Opus 4.5 is pretty insane. We are running 10 instances concurrently for a whole-app rewrite right now. Our codebase was mostly hand-written: Frontend - 700k lines of Typescript (React) Backend - 943k lines of Typescript Wallet/Vault - 28k lines of Golang We're migrating from regular React to Next.js, enforcing a high degree of quality & updating all of the styling. Manually this would have taken nearly 6 months. It would have been impossible for us to pull the trigger on a big project like this a year ago. With Opus, we're going to be totally finished in 4 weeks. Basically solves the "Tiger Team Trap" as described by Andy Hunt and Dave Thomas in Pragmatic Programmer. Whole team can contribute with QA & testing as well and feedback loops are super tight. Easily a 10x productivity boost, but software engineering is 100% not dead - engineers are more important than ever. It's like when hardware engineers ship bigger and badder systems then complain that software engineers end up eating all the resources anyway. Don't trust teams who say AI is shipping all their new features. We're going to see software get better, we're going to see it get bigger, and architecting systems that can be securely maintained by AI-augmented engineers will be the next big problem to tackle for researchers and engineers. Also AI still sucks at web3 stuff 🤷‍♂️ Anyway, the tiger team trap is easily a multi-billion dollar issue on its own & this is the first time I've ever been able to approve such a massive rewrite. Exciting times.
