This is a truly fantastic post. It isn't a rant. It's a story of enlightenment that I encourage all HN'ers to read and absorb. Disregard or play down the contents of this fantastic post at your peril. Understanding it and groking it could save you 5 years, 10 years or even a lifetime of writing software in the wrong way.
I have to assume you're being funny. Otherwise I'd like a batch of whatever it is you're smoking.
Not only is the OP mistaken as being almost a troll post but anyone who actually warns "er, no guys, this post is for real and you need to understand it or at least respect it to move forward in your careers" is also mistaken as "just being funny".
Just to clarify. No the OP is not a troll post or anything like it. It is deadly serious. And I am also being completely serious.
The OP is just someone who reached the end of his learning path of OOP. He found all its flaws and weaknesses and then discovered there is a whole other world out there called FP and that there are even languages which combine the best parts of OO and FP into one. Why is this considered a problem? Some people almost seem insulted by it. He is just trying to help you guys realise that the floor on which you're standing is not quite as solid as you mistakenly think.
As I said, it is a story of enlightenment. Discredit it at your peril, as you are only harming your own self development as a programmer. There is nothing wrong in learning FP and adding it to your toolbox. This doesn't mean you have to "give up" on OO. It just means you have two tools to select from rather than just one.
Observation: Unless they are famous or head up some popular OSS project, it seems that software developers are incapable of identifying or even respecting those who are clearly more knowledgeable/experienced than themselves.
