Over the years I've witnessed a lot of heated debates on HN... Is the JS ecosystem actually too complex? Is PHP really a fractal of bad design? Is learning vim worth the effort or is it all hype? Is golang fundamentally broken because it lacks(lacked) generics? Does anyone ever actually need k8s? Is nosql always the wrong choice?
