My long-time mentor had a spin on the idea: "The day you start a new role/job/position, look for and start training your replacement". The core notion is similar: it's not good for you OR your team/company/client, if you are a single-point-of-failure, irreplaceable contributor. And my mentor's spin puts a "selfish" take on it which allows some people to ingest it better - you'll never be able to take the next opportunity, if you have not left behind a working system for your current role. note: none of this is to say that ageism doesn't exist or that toxic / misguided work cultures don't exist. By all accounts, I would not personally want to work in an Elon Musk company, though I understand those that do. But if I have a super-high performer who is THE ONLY person who can move the needle on a number of high-value projects and is working 70hrs a week to accomplish that... that is a MASSIVE risk to the team and company, and needs to be addressed somehow.
