Well, I haven't read the same interviews. I merely asked to be given the links to those interviews. That's all. No rolling eyes needed.
Not for you! I was shamed, blasted, accused of trollism, and hounded by a few nuts for asking more or less the same question in the summer before the EOS R was announced. I generally took it in stride, though I was disappointed by the foggy, reactionary thought processes of some here, by an almost totalitarian rage for suggesting EF was entering its twilight phase, and asking what strategies would be useful when deciding about sale of current EF lenses--and future purchases.
Personally, based on my own reading of the scant relevant info Canon has been sharing, I think Canon intends to phase out EF over time, and that the RF mount is a replacement, not an addition. As I've said many times before, there will be a transition period that Canon will work out, that can't be clearly determined at this time by consumers or perhaps even Canon itself. Years? Certainly. A decade? Barely half that is my guess.
Though there were angry voices in response to questions about what to do with current EF lens collections, there was also a reassuring balance of members here patiently suggesting to, in short, "remain calm and carry on." To make lens purchasing decisions based on need. If the declining value of used lenses is a serious concern to some, to others it is an opportunity. And so forth.
Now I embrace the RF future. I have a 5D IV and L lenses that will work on whatever RF body I eventually buy, though early reports are suggesting "refreshed" EF updates are slightly tweaked to work better with RF bodies. The EOS R is not appealing to me, as I'd like a better sensor and improved ergonomics, etc. before upgrading from the 5DIV. But I'm sure Canon will develop the RF bodies to be clearly superior in most shooting situations, and Canon will have an expanding set of RF lenses. I don't want to have two versions of the same focal lengths, so if I'm very happy with a current EF lens, such as the ef 35mm f/1.4L II, I keep it indefinitely, expecting it to be as good as it is on the 5DIV when used on mirrorless. But I'm already saving up for the rf 50mm f/1.2L! If an ef refresh of this lens were announced at this point, I'd have to pass on it.
Future EF lens innovations? I doubt it. Some "refreshes" to update firmware for better RF performance? Tougher question!
Ah, how the camera world turns.
