P: New user interface lacks contrast and many usability cues, lots of other problems

I just updated to Photoshop CC(2015) version 2015.1. Adobe changed the UI to the flat look you see on phones and tablets. I do not see any way to select the classic interface, which I'm sure many desktop users of PS prefer.

This feels yet another attempt by Adobe to be trendy without caring about what users want or need. Didn't they learn anything from the dumbed-down Lightroom import fiasco?
