The main problem with being an arrogant, condescending, narrow-minded asshole who thinks the world is a simple place and you're smarter than everyone else is actually ironically rather simple: you're wrong. About so, so, so many things in this world. And the problem with being proud of it, as you clearly are, is that you deprive yourself of the chance of ever being any less wrong.

But you go on intentionally filtering out professional software engineers with over a decade of experience if they have even the slightest difference of opinion about the subjects you write about. Clearly they have nothing to offer you: you already know everything anyway.
