The thing I don’t like about the sorts of claims made here is that when people advocate for simplicity like this, they often just have a highly opinionated perspective of what should be simple. So they’re not really advocating for simplicity, they’re just advocating for prioritising whatever thing they think it is that’s important. Maybe that thing should be important, but it usually depends on the context, so you end up with bad general purpose advice, which usually doesn’t accurately portray the trade-offs it’s advocating.
