I still can't get over how competent Opus 4.8 is. In just a few days, I/it/we have solved a ton of problems I just gave up on years ago. I'm even learning things that I didn't even know I didn't know.

You pay for it though. But it's worth it if you have hit the wall on what you know how to do and have a drive to learn more. It's far less expensive than school, that's for sure.
