The particularly funny thing is how the blog admin - the author himself? - censors comments not to their liking, marking them as spam : ) They clearly are a bit touchy. Below, the comment he's deleted twice; you be the judge :) (I wouldn't normally repost, but the first time round I erroneously assumed it was due to including a link in it; apparently not). ---- The article has been commented extensively on Hacker News. I'm not pasting the link, as this gets my comment marked as "spam" (go figure), but it's trivial to find it with very basic google-fu. Now, while I don't approve of the unneccessarily biting tone of some of the remarks posted there, I think it's been demonstrated convincingly that a large share of this Kotlin critique is highly dubious at least. I believe that in general the longer we work, the less eager we are to learn new stuff, and we become more set in our old ways. It's only natural and human, but often we go to great trouble only to rationalize this attitude somehow. And that's what should set your alarm bells ringing. For the sake of your own development, nobody else's. Publicly criticizing a language without even knowing its standard library (as evidenced by the "Integer.tryParse" example, which indeed runs into troubles, but only because it's outright wrong - see the comments on Hacker News for more details) seems premature, especially for a veteran programmer like the author. ---- To me there are two takeways here; more important than Kotlin. Two factors that inhibit our professional development, especially in the long run, once we're "seniors" already. The first is what I already pointed out in the blacklisted comment, above. The other is sort of self-evident now; and that's the ego problem. Not only we become conservative over time; we also develop an oversensitive ego, and conversely, an allergy to being corrected. I really hope I won't fall into this trap myself... I sure as hell exhibit similar signs now and then
