Wasn't a dismissal, rather a comment, and technical language aside it stands as true: being happy "solves" problems collaterally, by rendering us oblivious to them.
If you don't want your comments to be read as standard internet snarkytropes, you'll need to distinguish what you mean more clearly. In this case, the trivialization of an entire article to an idiotic tautalogy kind of signals that.
On HN, if you have a substantive point to make, make it thoughtfully; if you don't, please don't comment until you do.
