It depends on where you plan to cruise, and/or how much you want to know.
If during the majority of your cruising, you will stay within 1-2 days
of landfall, I wouldn't be too concerned about having the ability,
except as something you would care to know about.
However, if you will be making longer trips, out of sight of land, I
would consider it well worth the effort and ability.
You don't really need to know all the why's and wherefores of what you
are doing, but mainly the steps involved in going through the sight and
various tables, to come up with a solution (or basic inputs, for a
computer).
Although the Naval Academy does not make celestial a required course,
the Maritime Academies do, for those going for a deck license.
In reality, the choice is yours ..... you can carry a whole bunch of
spare batteries and handhelds, or a sextant, tables, and/or a calculator.
GPS advantage - turn it on and it works G
Celestial - needs practice to be good, and some never do become good.

I am wrestling with myself as to whether to continue my USPS course
work and sign up for the JN course, which is the first of two courses
dealing with celestial navigation. I have completed all the electives
and through Advanced Piloting, so it is decision time. I have heard
that even the Naval Academy doesn't teach celestial navigating skills
any longer.

Is celestial anything more than an interesting exercise these days or
is it worth the effort to learn for any meaningful use? Ultimately it
comes down to time invested/benefit to learn, like anything else.

At the risk of sounding "lubberly", I just wonder if this is time well
spent these days.
