Very little changes in aviation at more than a snails pace. Ok the electronics have changed but the basic airframes are still very much like they were 50 years ago.
We have had the Canard idea but aircraft still have conventional wings, fuselage, tail with fin and elevators, a nose wheel and two mains.
The seating could change to a central pilot seat! Why left or right? or even staggered seats ( again tried) but we still end up with aeroplanes that have not evolved from what we had 50 years ago.
Even the engines Continental or Lycoming are things of the past so its only computers and sat nav which have brought changes.
Someday someone will come up with a revolutionary lifting device or configuration but till then NOTHING change
