Will it take far longer? I don't know... if they continue this push of implementing mobile features on macOS, trying to make it more and more like iOS. This seems like it could be a very effective way of alienating even more pro users. To an extent it has already happened. Seems like Apple has become unwilling to spend resources on features pro users want.
What, in your opinion, has Apple done to macOS to make it more like iOS that alienates pro users? Has any iOS-like feature of macOS actually prevented you from using macOS functionality? I'm using Sierra and honestly haven't even noticed much difference from the previous OS except for the siri icon on my toolbar.
In short: the pro user segment is alienated by Apple’s seemingly indifferent attitude towards them, and the increased integration, or synergy, of iOS with macOS does not help in any way. Generally, pro and power users want flexibility, options, customizability.
Apple seems hell bent on removing choice. Pro users were alienated when they removed firewire connectivity, you need adapters and dongles for just about everything now, and it’s not like this will be remedied with the 2016 MBP is it? Then there is the sad thing that is Mac Pro... That is how Apple actually forced a lot of pro users onto hackintosh systems, as unbelievable as that sounds, but you can run a hackintosh and have a better, more flexible, more performant, macOS experience, than with the real Mac Pro...
