When someone says PS they do not mean CameraRAW.

I never used Lightroom because I do not need it so correct me if I am wrong. To select a photo and to do a correction of a photo in LR one should import photos, view them, pick one, slide things and then export it. If one want to do the same thing with Photoshop they need to use at least three separate interfaces: file explorer, ACR and Photoshop itself.

It gets easier if the Bridge is used (is it still maintained?) but it still means the need to use TWO separate interfaces rather than one.
