I disagree. I think companies ought to develop for every platform, companies ought to create a market, but developers ought to specialize generally.

I don't think most developers are capable of being excellent at iOS development, web development, Android development, desktop development, etc.

Certainly it's not advantageous to specialize only in a particular language (particularly a dying or dead one), but that's quite different from a specializing in a particular platform.

If they have worked with developing in these many areas, they'd likely have some experience in each, but be not experts in any -- there are just too many.

If, as a developer or startup founder, you see yourself as someone capable of creating interesting applications, specializing in one particular client side technology isn't going to get you very far. Apart from games, I don't see many interesting applications built on iOS alone.

But the title of this thread is about "career advice", so if taken to mean "what's going to make me employable in the coming years?", Gruber may have a point. There will be a large number of jobs at ad agencies making cookie cutter "branded experiences" on top of iOS (unless it's swept away by HTML5). It may be a good career choice for people who used to specialize in Flash.

Personally, I don't find it particularly appealing to say the least.

As long as I'm concerned - UNIX is the only platform worth to build on for the long term. Anything else is just a temporary ripple in the ocean of technology on which everyone cashes up and leaves.
