Stupid click bait title -- they might suggest a single negative leap second.
Frankly, after reading about this I think we probably need to get rid of leap seconds, at least in the short term. The problems and potential problems simply are not worth the effort. Previously I suggested waiting until the clocks were "off" by 15, 30, or 60 seconds. Upon further consideration I think the lower limit before correction should be 60 seconds. In others words, long enough that either we will have lost the technology to measure time that accurately or it won't matter because every time keeping device of consequence will do the corrections automatically as needed.
