Steve Jobs was right all along. He believed a company should focus on a few products and do them very well.
However, he wanted to expand his vision into watches, cars, and the home. He put forth plans to build a bigger, better campus. He knew he would need more people. More great people.
It all makes sense. Apple doesn't have the staff to expand his vision. You can't have a team of 130 software engineers create OSX, iOS, tvOS, watchOS, music, CarPlay, HomeKit, research kit, iWork apps, pro apps, etc.
Since Lion we have greatly seen how hindered Apple is with frequent software releases filled with bugs and such. Apple needs more developers. More testers.
Apple can't continue down this track much longer without hurting its reputation.
I hope once the campus is complete and they triple their staff we will once again see great things....stable.
