This is the guy that got famous during the pandemic for suggesting ports stack containers 3 or 4 levels high vs the standard of 2 [1] [2] Turns out 2 is just fine.

That part was a joke because of Flexport's layoffs due to lack of volume. The stacking is probably a separate topic compared to the success of his business, but was just stating why his name and company are familiar on HN.
I personally believe they should stack them vertically vs horizontal stacking to save space so they are always accessible vs 2-3-4 high. (also a joke)
