Does the intellectual content/technological advancement in CS progress faster in industry, or academia?

It seems like companies are coming up with new things all the time, esp. in data science, machine learning, AI, machine vision, etc. Do these innovations etc. move quicker in industry or academia? If it's in industry, what purpose does academic research serve CS these days?

Few companies (Google, Deepmind, Microsoft among the most notable ones) come up with new breakthroughs, and that's mostly in ML. Most of the "intellectual advancement" (aka research) in CS happens in academia, though it often takes decades to be adopted in practice (by companies). CS is a massive field and the topics you mention are only a part of it.
