True local solar time for everyone. We have the technology.
Pittsburgh, PA
All discussions of daylight saving time policy are doomed by a mix of contradictory, inconsistent, and impossible preferences, which is why I think the only thing we can really hope to do is to make it worse.
In his 1987 book The Game of Words, Willard R. Espy offered a poem of “forgotten positives”:
I dreamt of a corrigible, nocuous youth,
Gainly, gruntled, and kempt;
A mayed and a sidious fellow, forsooth —
Ordinate, effable, shevelled, ept, couth;
A delible fellow I dreamt.
Correspondingly, he pointed out, many common words ending in -less seem to have no opposites ending in -ful:
A tailful dog, one leaf-ful spring
Set out for toothful foraging,
And as he dug in rootful sod,
Paid voiceful tribute to his God.
At which, a feckful, loveful lass,
Whose strapful bodice charmed each pass-
Erby, cried out, “O timeful sound!
O ageful, lifeful, peerful hound!”

Once I realized this, all those inept AI laundry-folding videos became hilarious.
