This has some crossover with ageism. In the last years in my org all the senior staff has been put to pasture doing either nothing or confined strictly to whatever they were already doing.

Some part of it is that we are perceived as lazy obstructionist naysayer dinosaurs when we point out any flaws in new projects as the article warns. But the rest is that because some of the elders were effectively semi-retired and doing little, anyone over 40 has been uncritically dumped with them.

So we keep the lights on while all the new shiny stuff is given to fresh juniors that don't ever push back and are happy to say yes, but also can't do it alone, and are lost at sea.

So they don't get anything shipped while we keep polishing our legacy turds and wince every time we accidentally get a glimpse of what they are doing.
