MacOS isn't going anywhere. We're going to continuously see iOS features come to Mac and certain enterprise apps and tools come to the iPad Pro. I firmly believe the Mac will always be around for Devs and people that feel more comfortable and grew up on desktop operating systems. it will just be seamless with iOS until they eventually merge or get as close as they can without neutering the OS. Apple has gone from a one sized fits all model under Jobs 3.5 inch iPhone, 9.7 inch iPad, few Mac models, to more complexity. It had to happen. An iPhone 5SE will fit some people, 6S for some, and 6S plus for some. We all have different needs. I can say for certain that an iPad Pro is the most accessible computer ever made. You go to an Apple Store on a Saturday and the Mac tables are all but abandoned with all of the children playing with the iPads. It's not meant to replace a computer for most of us. I firmly believe it's meant for these 10-18 year olds who have grown up on touch screen devices and will feel more comfortable on an iPad to get them through college. If your 60 year old mother wanted something to browse the web, send e-mail, read books, watch movies, etc you can't tell me that an iPad isn't better for her than a computer? That's the beauty of iOS...the simplicity. A 2 year old can pick it up to a 80 year old and everyone in between. My iPad Pro 12.9" has supplanted my Mac for 80% of tasks. Until it gets an IDE, multitasking gets a lot better, and something happens with ergonomics I'll still keep a Mac around. Even then I'll probably always have one. Make no mistakes about it though...the iPad is the future of computing. I don't care what sales data says. It was a new market and people don't upgrade their tablets every year or two. They hang onto them. I absolutely hate iPad's split screen though...absolutely terrible.
