Anyone who has a firm conviction in the law of kamma will find no fault with hawkings quote. Nothing is predestined. Everyone has choice. There is free will.
Whats left to speculate or debate about?
Of course opinions vary and anyone is free to post whatever they would like. For myself I like to keep things simple and focus on the present and what apply's to my daily life and everyday practice.
For me theres no need to speculate on the "illusory sense of free will" or anything else. It is obvious we have free will at each and every moment.
Whats important to me is making good decisions, acting with right intention and creating less unwholesome kamma. Thats why I posted Hawkings quote. Not to start a debate over predestiny or free will. Hawkings quote summarized it nicely for me:
There is always a choice.
If anyone takes issue with this then they take issue with Buddhas central teaching.
Tilts signature summarizes it nicely as well:
Kamma is ones means for going beyond kamma.
