Somehow even highly technical interfaces, e.g. DNZ zone editors are now made mobile-first. I wonder, is the majority of people really editing zone files on their phone? don't people value their time anymore?
Unless you're just reading a text-only article, there's a big difference between what a mobile interface can and should offer, and what a desktop interface can and should offer. I agree that we've sacrificed desktop for the sake of mobile.
I understand why this is done for sites whose goal is to show advertisements. If the majority of the users are mobile and you get most of your money from them, it becomes harder to justify creating a proper desktop experience.
I suppose I wish more people spent the time to build desktop-class interfaces regardless.
I think the sweet spot is mobile-compatible controls and progressively enhanced design that can scale up or down. Preferably using the simplest tools, even if unfashionable.
