+Zoltan Csikos This is a bit late, but from Google: "In computer architecture, multithreading is the ability of a central processing unit (CPU) or a single core in a multi-core processor to execute multiple processes or threads concurrently, appropriately supported by the operating system." This means that Kody Kurtz was making a joke about how this process could go faster if instead of only one array being sorted at a time after the array is divided, all arrays continue the process at the same time. It would be harder to keep track of visually, but the process would be much faster. Edit: Google is not a sentient being... at least not yet.

Any well designed divide-and-conquer strategy (of which Quicksort is an example) can (relatively) easily and safely be parallelized. That's kind of one of the major advantages of divide-and-conquer methods.

@@snap-off5383 the groups are guaranteed to be within a certain range after the initial sort. For instance in this video, after the 3 has been placed, we know for sure everything to the left of it is lower and everything to the right is higher. The point of using the groups, then, is to guarantee that we're not double-checking that 1 is less than 4 when we know that 1 is less than 3 and 4 is greater than 3 just because of where they are relative to the 3 after it's been placed.
