A little perspective is important here. I know
@Rafael Najmanovich in the real world. We are both members of the Montreal bonsai association. Here is my interpretation:
Rafael is also an academic, such as myself. We were trained (culturally and formally) to align our own thoughts and actions with the lineage of the work that has come before us. Rafa clearly has a lot of respect for Mirai, Jim Doyle, and Walter Pall among others. But academic or not, a lot of us identify those we admire and try to follow them in the ways we can.
Rafael is making an effort to produce videos on youtube on topics of interest to him. It's obviously reminiscent of Mirai, but he is doing it at his own pace and he has just begun. If you look through my thread and instagram posts, they are often done in a step-by-step or tutorial-like style. This is not because I am on an ego-trip, or that I think that I can teach everybody something about bonsai! Rather, I found myself adopting this style first because it is an efficient way to document and track my procedures with a time stamp, but also because some of the threads that I enjoy most--Sergio's and Brian's--are done in this way. Moreover, I often include in my posts (especially on instagram) a picture of a tree by Valavanis, Ebihara, or Sergio to illustrate the direction i would like to take my 2 year old cutting... There is a sense in which i view myself as 'following in their footsteps', in terms of both aspirations and practices. I think that this is what Rafa is doing when he is producing videos. There is a little Ryan Neil in his video. There is a little Walter Pall in his video. But the video is still Rafael doing Rafael, and that's something to respect.
If you want to critique videos on youtube about bonsai, there are much worse videos out there! Don't rip the guy just because he happened to share it in a bonsai forum. youtube viewership is much more diverse than this forum. But he has received helpful critique
here and elsewhere, and his videos are sure to get better with time!
