I imagine they have to figure it out the torque part and make it cheaper?

A lot of people have very bright, or sometimes not so bright, ideas to make the bicycle better. These ideas look good on paper.
Once the prototype arrives in reality, some(most) discover that the devil is in the detail:
The surprisingly high forces and torques.
How hard it is to build something that still works when not every tolerance, gasket and bearing is at 100%. That still works in the rain, with sand and grit and dirt, without weighing a lot and producing a lot of friction, and production cost.
Then the brighter ones of those inventors see that a chain over two sprockets does exactly all that, in an affordable, reliable, few-parts-needed way.
The brighter Inventors leave it at that. The others, they go find venture capital, produce shiny CGI videos, get enthusiastic news coverage for a few years, and then vanish in a puff of Pedro's chain lube.
