Don't let an opinion piece posted to Hacker News do much to influence your choice of languages. Everyone has opinions and most of them are equally valid (or invalid). If you want to write mobile apps, you're pretty much stuck writing in those languages or using a framework that does the cross-platform shenanigans for you. Or writing web apps exclusively that have mobile browser support. Regardless, neither Java nor Obj-C is going away anytime soon, so it would not be a mistake to learn either or both.
