chances it will be around in 10 years? I would say 25%.
Also now that Discord exists, I would never do a voice chat in Skype either. A substantial portion of every Skype call I've ever been on was people apologizing to each other for the bad audio. Discord apparently just has better signal processing.
Skype for Business does. But... not the Azure/Cloud version; you have to host it on-site, and MS are rapidly replacing Skype with the less feature rich (if that's even possible!) 'MS Teams'.
None of the chat apps ticks all boxes, which is why we need a universal client that puts the user back in control like in the Trillian/Adium days. And no, matrix+bridges is not that solution.
