Taking this as an earnest question—no, I don’t get that sense from that word. To me it describes the direction of an error, not the error itself.
It’s a thing you’d prefer to avoid, sure; but some degree of prognostic uncertainty is totally routine (in fact I would call that definitional: no predictions are truly certain until they’ve come to pass, and by the time that happens it’s usually too late to act). It’s not “bad” any more than mortality is “bad”—it just is, whether or not we wish it were; wisdom lies in managing it as best you can.
In the sense that the gp used the word, I think they allude to a tradeoff: you can reduce the probability of an underestimate by increasing the probability of an overestimate. I took their comment to imply that it would be wiser to risk an overestimate than to risk an underestimate on questions of “can Chinese society achieve a massive goal on a tight timeframe if their leadership decides it’s important.”
No I get what the GP meant. Your comment sounded like a triviality from Lapalisse a bit, because I cannot think of any occurrence where underestimating something is a good thing. Bit like “15 min before my death I will be alive”. But Lapalisse too didn’t mean it literally, he just wanted it to sound like that, it seems it’s what you did.
