alt Hacker Newsyou could however link to the timestamp where that particular explanation starts. i am afraid i don't have time to watch a one hour video just to satisfy my curiosity.

This is approximately the section in the video titled "Memory controllers hate you" (https://www.youtube.com/watch?v=KKbgulTp3FE&t=1399s), combined with the following section.
The actual explanation starts a couple minutes later, around https://youtu.be/KKbgulTp3FE?t=1553. The short explanation is performance (essentially load balancing against multiple RAM banks for large sequential RAM accesses), combined with a security-via-obscurity layer of defense against rowhammer.
I've found Gemini useful in extracting timestamps for particular spots in videos. Presumably it works with transcriptions, given how fast it is.
The three answers it found were:
- Avoiding lock-in to them: http://www.youtube.com/watch?v=KKbgulTp3FE&t=1914
- Competitive advantage: http://www.youtube.com/watch?v=KKbgulTp3FE&t=1852
- Perceived Lack of Use Case: http://www.youtube.com/watch?v=KKbgulTp3FE&t=1971
Those points do actually exist in the video, I checked. If there are more, I don't know about them, as I haven't yet watched the rest of the video.
