The End of the Apple Magic?

I have just read what Apple shown at the WWDC 2016.

In the 1985 Windows 1.0 was born. In a snap, the IBM compatible system evolved, and the competitive advantage of the Macintosh dried up and disappeared.

IBM PC was cheaper and way more open.

Like in the 1985, now in the 2016 the iPhone revolution has come to an end. After the Retina Display introduction, no real new feature was introduced. The apple Watch was beaten by competition.

Two years passed with no true innovation (i.e. Apple Watch is not a revolution).

The last MusicApp removed the beautiful cover navigation, and try to sell you the apple music rent service all the time, instead of let me play the music I have already bought.

If the WWDC2016 breaking news is a new file system, it is a very poor gift. I am writing this note on a Windows 10 PC. It is not a shining operating system it freeze a bit and has still a very ugly backup engine, but MacOSX is not the “most advanced operating system” anymore, like it used be in 2000.

MacOSX is the oldest one nowadays.

Historically Apple system are very closed. The reason is simple: when you go to your shareholders and ask for money, you can show you have a competitive advantage, a strong set of feature no one can take apart from you. But Apple lost this war in 1985, when the high pricey Macs cannot compete with open IBMs clones.

To be fair, IBM could open to clone market because its business was on high-end server, and Microsoft alliance will help to sell more IBM PCs.

Negli ultimi 20 anni sono successe tante cose imprevedibili. Nel 1995 nasce Java. Nello stesso periodo nasce Erlang. Java inizialmente segue la strada culturale tracciata da Sun, e si configura come un linguaggio estremamente verboso, con API specifiche per la gestione della concorrenza (es keyword synchronized per gestire nativamente le zone critiche che necessitano di mutex). Inzialmente Java è per far girare applet, poi Sun presenta un chip ad hoc (picoJava) poi IBM ci mette del suo e il linguaggio si trasforma in una ottima piattaforma per lo sviluppo server side.
