Apple's design lab used to be amazing at balancing usability vs design. It feels like that has tipped far too hard towards "thinner at any cost" as a design philosophy, and that's come at a cost of clean lines and product quality. The design lab doesn't need reigning in as such - Apple needs someone who can challenge them at a senior level and call them out, which Jobs did and it feels increasingly like nobody else has ever replaced.
Agreed. There was a thoughtful pragmatism to Jobs-era Apple products. That pragmatism is gone.
