How Competitive is HCI?

I am a Bachelor’s Student in Computer Science.

I am looking to get a Master’s Degree from a top university, and I was wondering how competitive HCI is compared to a field like AI.

Will it be easier to get into an AI program and switch to HCI later if my ultimate goal is Product Management? Or is it possible to get into Product Management with an AI degree?
