This is getting silly quite honestly. It is difficult enough to take the Doomsday Clock seriously as it is, what with its constant flopping back and forth and the use of a unit of time as an analogy for a situation that can actually persist for an indefinite period of time; but until now the analogy of "only so many minutes to midnight" at least could be tolerated as a generalized symbol of proximity. Two minutes is "closer to doomsday than" three minutes - yeah okay, fine.
But now "100 seconds"? That's rather absurdly specific, and the fact that we're now suddenly willing to subdivide minutes to account for new developments when previous world events just as momentous were adding or subtracting two, three, four, or even more whole minutes at a time, just completely and totally undermines the whole message of proximity and urgency that had been conveyed up to this point - much like a parent threateningly giving an obstinate child "to the count of three" to obey and, when the child is not moved by "two", continuing with "two and a half" and then "two and three-quarters". Before today, we were at a presumably panic-inducing "two minutes to midnight", but now we find that peace-threatening circumstances are capable of bumping the counter only 20 seconds or so, and suddenly "two minutes to midnight" isn't quite that close at all. And as more bad things happen and the world becomes more unstable but "doomsday" continues to not arrive, eventually major tremendous developments are going to be capable of nudging the needle only a second or two - and then later still by only fractions of a second. It's like some kind of new-age take on Zeno's paradox.
