I also liked the interview!
In particular, I found the quote below very interesting, namely that a small rule change such as "group tax" would make KataGo play more like Takemiya

As an amateur, this means one has even more reason to play their own Go style, instead of trying to mimic AI, since the difference in outcome of the game is too little to matter (unless one is pro), between regular rules and group tax rules.

One fascinating thing about the ancient "tax" or "stone scoring" rules is that they seem to slightly encourage a more cosmic-style of play. Because the penalty is increased for making multiple small groups, this means playing lots of big global moves and making large frameworks becomes more favored. For example, under these rules, 3-3 invasion appears to be no longer a good move to play early, and fighting for influence on the sides and center becomes more favored too. For people who have been a little disappointed about the high value that modern AIs place on the corner territory and the resulting tight style of game, perhaps these ancient rules might feel refreshing.
