Incredibly dismissive of somebody's work, aren't ya? I regret breaking my own self-imposed rule of never answering follow-up questions on HN because there's always some dipshit willing to hand-wave away six months of my life and 40 years of real-world experience with a flippant comment of "oh, but that's easy if you don't have too..."

Fragile ego too.

And you sir, are fucking toxic, just looking at your comment history I can tell that. So you calling me "fragile" carries about as much weight as the next idiot with an opinion.

Toxicity is in the eye of the beholder.
