> These models lack the taste that makes for effective product decision making. It is cheaper than ever for a product manager to say "Someone complains about this on reddit, let's implement it", while the tasteful leader says 'No, that's not what our product is. Making that means we commit to it for a long time and our customers really want {something else we already do, but not perfectly} instead.'

This is a very good point. It's now easy to just do things, so discernment has become more valuable than ever. If you leave things to Opus 5.5, it'll just say that you need to implement every product-bloating change, and "here let me take care of that for you".
