I have nothing against spontaneity, but waiting for everyone and their grand-daughter to get to the stage for the acceptance speech of the main award (awards at the Emmys) takes up valuable scheduling time that might better be spent in allotting more time to In Memoriam segment where time constraints are always the excuse for leaving someone important out. That, and eliminating stunts like the tour bus nonsense.
A screw-up like the one accorded Sammy Davis, Jr. in 1964 can be fun, i.e. announcing the winner in a category other than someone in the category whose nominations were just read, which harms no one. Granted, the screw-up on Sunday night allowed for a seminal moment, but suppose it had been the other way around, with the underdog, Moonlight, having to relinquish its award to the front-runner? It would have been heartbreaking. Suppose it had been front-runner Viola Davis who was mistakenly announced as the winner when it was actually Naomie Harris who won? They might have had to take poor Viola out on a stretcher.
I do agree, though, in this Facebook-Twitter age of instant news, there's just too much of it. We really didn't need to see the evidence of the PwC guy with the two envelopes in his hand. It would have sufficed to know that the accountants messed up and won't be back at the Oscars.
