I feel you are concentrating on a very small and negative part of the post in a very disingenuous manner.

I read the article more as: "I have found throughout the years I've become a decent programmer in iOS and Android, I'd rather be a good or excellent iOS developer."

The end just briefly describes why he decided to go with iOS instead of Android briefly, but that's about it.

You're clearly still young and haven't yet burned out on learning new technologies that (a) are just poorly thought out rehashes of existing technologies, with everything renamed to sound new, and (b) go obsolete within a few months, flushing your precious time investment down the toilet with them as they go.

Eh, I think it is a natural process though in one's professional life. Especially with something like phones where the complexity has just exploded within each platform. The number of ways to deploy code on iOS alone (ObjC, Swift, Cordova, React native, etc.) has increased rapidly, and the size of the system apis alone has increased massively. Some form of specialization is likely inevitable. There was a time when the web only had webmasters, and they did everything from devops to backend to frontend. Gradually it became handy for a lot of people to focus their professional career on one area they were particularly good at, especially to move to the absolute peak of their potential.

By all means people should try out things, and keep up with things, but for a lot of professional reasons it makes sense to have a core competency. Of course it also makes sense to move that as needed.

I have little patience for learning the same thing over and over but only slightly different. It's just a big waste of time. There's no enjoyment or happiness down that path.

Learning totally different and interesting stuff, that's a whole different story.

OP is not lazy to learn, it is just that he finds out that learning android development is a poor investment. He would rather learn swift instead, which I think is correct.
