the dream is over, and the company is on the verge of decline, like it was in the end of the 80s.
Computers are becoming ever more ubiquitous, and Apple has laptops, desktops, tablets, watches, and a music service, cloud services, some presence in the living room, a bit of AI, and a long history of OS development, plus has a track record of approaching new form factors with a humanist perspective on design, and a presence in many shopping malls, with stores often very busy, and lots of money, for now.
Yes, everyone else can do a part or parts of that better, like, maybe I'd rather have a Lenovo P50, if I was an architect, or you must have a phablet, because your company is based on Google Docs, but for a lot of people, buying into a system is more like a marriage, you get what you can and stick with it, knowing it won't be the best at everything, because change is a pain and perfection a mirage.
Apple would have to screw up a lot of things at this point, to enter real decline. Doesn't mean you have to go anywhere near them with a bargepole, but saying they or their dream is over, is a bit silly. There isn't a heck of a lot new you can do with a laptop, and someone has to decide the balance of features, and they won't suit everyone.
Maybe in 10 years, when AI has gotten somewhere, we can ask if Apple is over.
