...and one has an opportunity to feel like an absolute idiot when handed a phone with God knows what camera app to take a group picture under complicated stage lighting, where simple exposure triangle controls are hidden under God knows under what nonstandard UI element - seen or via gesture. Because you're photographer and you should know better!
But all I needed was ages old shutter speed/exposure adjustment controls...
You need 500 page manual for apps too.
//Joke, but not really. Another reason I prefer mechanical: controls are there right on the camera body next to my fingertips, ready to be accessed right away not under 3 Menu layers...
And when I found ISO setting in the app and adjusted it to better match the lighting, it behaved 180° opposite of what I expected - dialing in higher ISO darkened the image, because reasons not communicated on screen and something cute from that exposure triangle being locked under a different series of menu... and people on stage are waiting on me fiddling the controls, making remarks already
Why do this?
