What happened to Pluto, where did human intelligence gone wrong?

They say Pluto's path crosses into Neptune, though Pluto is round,
orbits the Sun and
has Moons.

The problem with the logic: If Saturn's orbit would cross with
Jupiter's, first of all which
one would not be a planet then, second, how can you 'dismiss'
something we see as
a large planet?

Pluto is a planet.

Humanity is declared mad.
