There's a tool I built at work that, per my director, is saving Dell $1M a year at the least in operational expense. I go away, and there's no one to manage the tool. My teammates are capable to learn coding but they've got their plates full too.
Would this be ( in general, not specific to Dell ), a good approach to being layoff immune or what would be a way to live your life as an individual contributor in big tech companies and not worry every day whether you'll login to your computer successfully?
