One reason why the latter may happen is that f0 possibly becomes so complicated that it’s “hard to attach more behavior to it”; maybe it’s just simpler to create an entirely new module that solves this task and doesn’t care about diamonds. If something like this happens often enough, then eventually, the diamond shard may lose all its influence.
I don’t currently share your intuitions for this particular technical phenomenon being plausible, but imagine there are other possible reasons this could happen, so sure? I agree that there are some ways the diamond-shard could lose influence. But mostly, again, I expect this to be a quantitative question, and I think experience with people suggests that trying a fun new activity won’t wipe away your other important values.
