You are right, finding a forced mate from this "root position" needs a brute
force search at some 24 or 26 ply, and that's way too much for engines these
days to solve in a reasonable amount of time.
But maybe that won't be necessary. We tend to extrapolate technical developments
very linear into the future like a single rubber band, because obviously we are
not able to foresee new developments -that is: *what* those developments are!
But we also can't foresee combination of technology that might change the way a
chess program will be able to work in the future.
I always remember a small booklet from 1956 just after the Sputnik was launched
and a (little panicked) American author thinking of new weapons, like ICBM's.
How to guide those to their destination? Some advanced possibilities were
offered, like launching a lot of them after each other so they could keep
"eyecontact" with each other over the horizon, relaying information to the man
steering them. He -of course- wasn't able to see the combination of sattelite
images, GPS, microprocessors, software, and very efficient propulsion systems
that created a device like today's cruise missiles singlehandedly seeking their
*own* way.
Maybe future chess programs will make use of new combinations of technology, an
can make use of other AI developments and use e.g. pattern recognition like
today's strong chess players do. In that case they have the both advantage over
human players on "insight" and on "calculation skills", including brute and
selective searches. I doubt if it will last twenty years.

I let RC think a bit further:
