Something seemed off about this list as it suggested “rocket science” in this field is MapReduce from Google. Turns out this list is from 2014 [1], reader beware, as things have changed since then.
This definitely puts it into context — it has been ten years since this list came out, and at that time, it had been ten years since the MapReduce paper came out.
