I would imagine Higaonna-Sensei, being a humble and quiet man, has had to do a lot of soul searching to feel comfortable with being in so many photos and videos. I'll bet that, at some point, he made the decision that he would have to allow himself to become widely known and loved all over the globe, because he had a message to teach and a promise to keep for his own Sensei. I'll bet he's had to be careful not to abuse his power or take advantage of the privilege that he's been afforded.
If he's anything like the teachers I know, he's also given up countless experiences, freedoms, and luxuries that come with the poverty that teachers often incur, with everything they earn going back to their students.
I wish there were a way for me to see Higaonna-Sensei again. I miss him a lot. I would tell him all about how my Sensei is careful to follow his work, how in our school we pay attention to character as much as to technique. I would tell him that I'm still loving karate and that I'm doing fine. I would tell him that I'm even more enthusiastic now about karate than I was when I began, and that it's led me to a healthier and happier life.
Most of all, I would thank him for all he's recorded and written to officiate the legacy of Goju Ryu Karate-Do, that we are listening.
