CS DH and AI specialization?

Hey, possible incoming CS student here, and I was wondering if it’s possible to do both the DH and AI specialization while in CS, and to hear from anyone who has done that and what their experience was.

Experiences from the DH specialization would also be appreciated, and their insights into how getting a firmware job has been for them.

Also, do u HAVE to do sequence 4 for DH, or is it jsut recommended, i would rather do sequence one.

Finally, how is the courseload like? Do u think u would’ve been better off just doing CE, or does this still give u the free time that CS ppl use for side projects.

Thanks to any who answer any question.
