There's a long list of things that have "replaced" humans all the way back to the ox drawn plow. It's not sane to be angry at any of those steps along the way. GenAI will likely not be any different.
It is absolutely sane to be angry at people's livelihoods being destroyed and most aspects of life being worsened just so a handful of multi-billionaires that already control society can become even richer.
it's plenty sane to be angry when the benefits of those technical innovations are not distributed equally.
