Thank you for answering my question; it turns out that our positions
are more in agreement than I had thought.
I do not believe that abolishing leap seconds will mean our official
time will depend solely on Cesium atoms, with no connection to the
rotation of the Earth. Rather I believe that abolishing leap seconds
will require a future generation to re-synchronize official time with
the rotation of the Earth, as was done with the seasons in 1582, and
that it is wrong of us to force that burden on them for our
convenience.
Imagine that you are Julius Caesar, reforming the calendar. You have a
choice of leap year algorithms: every four years, or a more complex
formula that keeps the calendar closer to the astronomical year. Your
astronomers urge the latter, but you are conflicted: the simpler
formula is more likely to be applied accurately, but the consequence is
that a future generation will have to skip 10 days and adopt the more
complex calculation anyway. What is the right choice to make?
In Caesar's case the civil servants who managed the calendar after his
death couldn't even count to 4 accurately, but computers are better
today.
By the way, I am not a Brit; I am a mostly-retired computer programmer
living in New Hampshire, USA.
