Of course nothing lasts forever in the greater scheme of things. Even the sun is expected to eventually burn itself out if the scientists are to be believed, but none of us will be around long enough to witness that.
What irritates me isn't that Apple is doomed. It's that much of the tech gadget press seems to be driven by the desire for something new (and which is not already controlled / dominated by Apple), which then leads to breathless coverage of fads and flops (eg: smart speakers, folding phones, VR) while the real paradigm shifts by Apple (eg: wearables) are not getting the coverage and attention as they deserve. In short, people are falling over themselves to bash Apple for the sake of clicks and views, and there is little desire to actually understand how Apple works and thinks as a design-led company and objectively cover what they do.
Let's say that Apple will indeed be doomed in another 20 years. Someone parroting that refrain for the next 2 decades will eventually be right, but in the process of getting there, he will also have been proven wrong enough times that in the greater scheme of things, he's still so very wrong even if he does end up being correct in his prediction.
But yes, I do believe that Apple will go on to be insanely successful and profitable for a good long time to come.
Personally I am beginning to think Apple might be getting close to the "Lumbering Giant" position.
Perhaps not yet, but give it another 10 years?
Without question they are suffering in some regards already due to their size, and don't really feel a very dynamic company anymore.
They feel like they dare not experiment, everything has to be very slow, very carefully thought out steps as they are unable to move fast.
A bit like a Aircraft Carrier.
That's not bad, but it makes them unable to be very exiting.
What I'd like to see, genuinely, and I don't know if this would be possible, would be for Apple to spin off a seperate division that was allowed to be more dynamic and take more risks.
So the Juggernaut Apple could continue to do what they do now, but the new "Apple Lite" could work on other things that the main company dare not venture into as there is too much at stake.
IT would be fun to see this. A bit like some of the far east phone makers, where you have the parent company which has to play it safe, but they have other sub company/s that are allowed to experiment, but without damaging the main company.
We all know Apple look at products on the market, Look at tech others invent, sprinkle a little of their own design and tweaks and then Boom a product arrives.
Then you wait a year and Boom version 2 fixing version 1 arrives.
Five years later we have an excellent mature version.
Meanwhile Apple-Lite could have released 20 things for customers to play with.
Many will fail, much fun will be had, and some good results learned.
It's always the same, Companies get too big and can't afford to take risks, or have much fun with designs.
I'm sure and Apple-Lite could have had quite a few Apple Watch designs out there by now.
