i think thats a bit of a damning assessment. dude just has a short attention span, doesnt mean you know them well enough to say what "kind" of person they are
These videos are more than one narrow, they give demonstrations, examples, visit restricted areas and get to touch reallly cool machinery. This isnt a 3 minute speedrun world record stretched to a 45 minute video.
Even those 3 minute speed runs can be 45 minutes long because they're explaining all the glitches and tricks they're using in the run and showing all the nuance you wouldn't get in just the 3 minute run.
Why would you announce to the world that your attention span is so short and your interests so shallow that you can't possibly fathom anyone watching a 30-minute video on an interesting topic?
