I agree; and it's probably not as deep either. I meant that computer science has staying power, while particular branches (or JS frameworks) may rise or fall in popularity over time. Likewise, the "trunk" of data science knowledge is not a mere fad. I'm not a data science academic or practitioner. My opinion is based on a small amount of tinkering and what I've read in various online sources.
