I love Julia for AoC, especially for matrices. It's just that good and I'm surprised more python people don't use it.

Every language has their own conveniences but, I agree, Julia is well-suited for these types of problems.

I’ve used Julia previous years but I didn’t use Julia this year because it’s been more difficult to gain traction with it professionally.

Python's numpy has great support for matrices and all kinds of matrix operations.
