Not yet... You may have noticed that so far each of them
carried a composition date of either January of the new year
or December of the preceding one.  In 2050 I'll be 84 years old,
and hope to still be capable of constructing a 2050-solution problem.
Of course others can compose such puzzles too (or search for them
by computer, I suppose, though then it will often be unreasonable
to expect humans to understand and solve them).
