Garbage. If your mind were made of clockwork, why would you expect it to *feel* any differently from how it does now?
Free will exists by definition. We define it as "that process by which humans make conscious decisions". That leaves the question of how we make those decisions completely unaddressed. How do you think we make those decisions? Just what exactly do you think our brains do, anyway? (No homunculus, please.)
Please, no profanities. :-)
Aaah but what is consciousness? What is conscience? What is the materialistic explanation for either? Quick answer - materialism cannot answer either question. How can matter make non-deterministic decisions? Matter can only act through necessity, through being acted upon by forces beyond its control. Indeed matter cannot control anything, it is controlled by so called "natural forces".
