Over 30-ish years of work, I’ve lost about 0 coworkers without warning or transition to lotteries or similar events, and more than a few (whether permanently or for an extended period) to unexpected sudden death, injury (traffic related being particularly common), or other unheralded misfortune (law enforcement involvement, on a short out of country trip and then encountered visa issues, whatever.) “Bus factor” is a more realistic reflection of the threat model, and resonates with experiences anyone who has been working more than a short time probably has more than “lottery factor”.
