- if LQG is unsatisfactory

it's come to my attention that there are arguments that loop quantum gravity is simply wrong, and specifically in the way it method of quantization of Ashtekar variables.

So what are more promising ways to canonically and nonperturbatively quantize Ashtekar variables

Ashtekar variables are also used in Woit's Euclidean Twistor Unification. the standard loop approach appears to be wrong, what are ways to fix this then?

lastly, is correctly quantizing Ashtekar variables is promising approach to quantum gravity?
