UX Pro here. Google pays senior UX folks an average $160,000 they have "degrees" from third rate Unis like Stanford and Cal Poly tech.
How dumb can they be? Do you think they will ever make any money?
That's precisely what I find scary about those UX changes: they to run counter-current of everything I value in UX (clean and compact vs. bloated and spread out).
The new GMail seems like a more functional “new Reddit”. It achieves a certain look and was probably metric driven, but didn’t really address what users care about.
As a casual GMail user, I like it. But it would drive me crazy if I had to work with it all day with my work mail volume.
