Look, I am in fact a career academic. I know exactly what's attractive about it, I've made considerable financial and personal sacrifices to get myself to a position where I can work in a university environment and spend my time doing groundbreaking research. And yet. The gateway into this life is a PhD, and the PhD system is deeply, deeply fucked up when it isn't actively abusive. Doing a PhD will break you. It's pretty much designed to break you.
If you have every admirable personal quality you can think of, if you have every advantage in life, still, getting through a PhD will grind you down, will come terrifyingly close to killing your soul and might well succeed. It will do horrible things to your mental and physical health and test to breaking point every significant relationship in your life.
