Success always comes before the fall - Apple can either stabilise or fall. They will fall.
Linux won - Android is Linux. Consumer electronics are Linux. Servers are Linux. Everything runs on Linux. Microsoft is done.
Google wins. I own Google now.
Linux was winning before Google arrived, and Google still would've won had they used BSD instead. Nobody cares what OS is running underneath google.com
I find it thoroughly creepy that we define success through growth in a finite world. If a company isn't growing, it's "done".
I realize that isn't quite what you mean, but then you shouldn't write it. The mindset is actively destructive.
The current capitalist system revolves around rich people making more money because they are rich - that only works if they invest in companies that can return a [quick] profit.
It is very sad.
Mature companies are like bonds - I don't invest in them because they don't generate enough capital in return for the risks taken.
This is old and beaten ground though, which you are no doubt familiar with. I'll refrain from treading it again.
Also "open systems" always win ? Linux would like a word with you.
