That begs for a very simple answer.
Because TC's are subject to optical physic laws and these cannot be
twisted in any way.

Lens technologies will improve on many parameters like weight, size,
dispersion etc, etc, but only within the description of the said laws.
Right now today, with current technology we can't bend the physics involved.
