What utter tosh!
Maybe my irony radar is switched off but come on!
The SLR form is perfectly braced for hand held shooting, mirrorless with live view is not.
Thats before you get under the hood.
For the folk who need WLF's nothing other than a WLF will do, for the folks who need an SLR form, nothing else will do, for the folk who like rangefinders, nothing else will do. Part function, part form, part technology.
Everybody want to kill off DSLRs, yet nobody really wants to buy into mirrorless.
Get your stories straight and stick to them.
+1 Try using a mirrorless with the sun over your shoulders glaring on that screen. Anyone that has used a viewfinder would miss it. Try having a mirrorless with a large sensor and a 400+mm lens hanging off the pathetic grip, and hand-holding a shot. I'll keep my camera pressed against my face, thank you.
