> Over 40 dev (Individual Contributor - IC as they call it) here and all I can say is that the article is completely ignoring large companies like FAANG, Microsoft, etc where ICs are allowed to remain ICs (design, write code, mentor juniors, etc) and they thrive given the right scope. 30 year old IC at a FAANG right now, and IMO if I'm still an IC at a FAANG when I'm 40, things have gone horribly wrong. I'm saving upwards of $200k per year, not including my actual retirement accounts.
