Or like many a company that prefers to paper old hands with cash to keep an old system running until it is really, really no longer feasible.
Banks and airlines are the most common example, many of them run on mainframe systems with code that's old enough for humans to go into retirement - and replacement projects usually tend to go into the billions of euros range with many of them failing catastrophically.
Even paying some greybeard 500k a year to deal with that stuff despite him being retired is far more profitable in the short term. That's the problem with letting beancounters run the show because eventually, there will literally be barely anyone left alive who is capable - and even less who know all the "implicit knowledge" behind edge cases.
