You can `cargo clean --workspace` now, to avoid rebuilding the dependencies

Sure. But any nontrivial C codebase will have UB regardless of your intentions. This has been proven time and time again.

But are they "no UB in the code" great? For my use, Opus is absolutely good enough at Rust

Yeah, it's almost always more effective to work with an existing project as a starting point

They could use MPL. It's an alternative "weak copyleft" license that's not concerned with dynamic linking

The added value is that it can iterate autonomously and finish tasks that it can't one-shot in its first code edit. Which is basically all tasks that I assign to Copilot.

The added value is that I get to review fully-baked PRs that meet some bar of quality. Just like I don't review human PRs if they don't pass CI.

Fully agree on IDEs, though. I absolutely still need an IDE to iterate on PRs, review them, and tweak them manually. I find VSCode+Copilot to be very good for this workflow. I'm not into vibe coding.

This. If you use a modern frontier model like Opus 4.5, there's nothing to learn. No special prompting techniques. You give it a task, and most of the time it's capable of solving a big chunk quickly. You still need to babysit it, review its plan/code and make adjustments. But that's already faster than achieving the same results manually. Especially when you're at low energy levels and can't bring yourself to look into a task and figure it out from zero.

Sure. But for now, this is a competitive space. The competitors offer models at a decent quality*speed/price ratio and prevent Anthopic from going too far downhill.

Actually, as I think about it... I don't enjoy any other model as much as Opus 4.5 and 4.6. For me, this is no longer a competitive space. Anthropic are in full right to charge premium prices for their premium product.
