I think it means that as people get older, they get crankier and thus more prone to rush to judgement, just to move things along quicker, rather than take the time necessary to figure out all the nuances and expend patience in trying to actually change things. Though I might be putting words into their mouth.

Although either way I definitely have noticed this trend within myself, especially when I was on Reddit, so it's a real shift imho. And it needs to be fought against vigorously, bc talking rather than listening usually does not lead to the most ideal outcome. That's what I got out of that anyway.

And there's a MAJOR caveat: sometimes judgementalness should be embraced - e.g. patience to tolerate a tanky will never work out well... (The only thing we must never tolerate is intolerance). Young people tend to be too patient sometimes, even as old people trend towards being too judgemental. Young people need to learn more and realize what is known vs. not known yet, and old people need to aim to practice discipline to avoid their feefees from taking over logic as they are always wont to do if given half the chance. imho ofc, which is surely incomplete!:-P
