Opportunities have been missed. Just one example: Apple could have owned the DIY video content market, as they did with audio podcasts and apps, with all the synergies for hardware and software sales and training that would have created.
Instead they've handed it to Google/YouTube.
Apple is practically indestructible as a company at the moment, but I can't see the momentum continuing ten years from now without something new and amazing escaping from Cupertino - maybe like Amazon's Echo, but even better.
Jobs succeeded because he could always be persuaded to leave a space for users to add content. Podcasts did that, so did apps - and both changed the industry.
Cook seems more like a top-down kind of a guy, and less focussed on users. That's not a good thing at all, IMO.
