Yes, also a good minor when paired with other majors. You will learn important fundamentals that are timeless.

For what goal?

I'm looking to go into CS industry, maybe work on AI type things (I have tons of AI related ideas but not the experience to execute them), or to pair with another field such as business, economics or law

Then you'd better at least minor in mathematics, focusing on topics such as number theory, discrete mathematical structures, linear algebra, and modern algebra (studies groups, rings, and fields). This will provide you the mathematical background you're going to find useful for studying AI.
