Highly disagree.

Fuseki (opening) doesn't matter much for most players. AI confirmed that a wide variety of openings, even weird ones far removed from the usual credo, work very well. At worst you may lose a couple points in doing so, but unless you play at a high level that's negligible and will never be the reason you lost.

Joseki (corner sequences) is also not that important, and certainly not something any beginner should spend time on. In fact, a common Go proverb is to "learn Joseki and lose two stones" (get weaker). We often see beginners learning Joseki, getting confused when their opponent doesn't follow the sequence they have in mind and ultimately blundering their corner. Or they ask "how to punish that?", without realizing that many moves are good even if they are not Joseki, and there's nothing to punish.

These tutorials don't even teach horse-move, 1-point jump or similar movements though.

With so much emphasis on cut and strong play, anyone completing this set of tutorials is going to be an absurdly strong tactician and then lose 20 points as the opponent horse-moves around the board.

Surely you've played the beginner who favors tactics and capture at the expense of easily captured territory? Given this set of tutorials, do you think any beginner will understand sente, gote and tenuki? And even if a beginner somehow understood it, what basis of play will they have? There's literally no tutorial or discussion on walls, influence, 2-point jump, 1-point jump, strong vs fast play (etc. etc.)

Sorry if I'm missing something but are you responding to the right comment? Your answer doesn't seem related to what I said.

I'm also not sure how that relates to your earlier point about "Joseki", which I was disputing (like many others).
