1. **State the problem:** Solve the inequality $$|x^2 - x + 1| \geq 1$$.
2. **Recall the definition of absolute value inequality:** For any expression $A$, $$|A| \geq 1$$ means $$A \geq 1$$ or $$A \leq -1$$.
3. **Apply this to our problem:**
$$x^2 - x + 1 \geq 1$$ or $$x^2 - x + 1 \leq -1$$.
4. **Solve each inequality separately:**
- For $$x^2 - x + 1 \geq 1$$:
$$x^2 - x + 1 - 1 \geq 0 \implies x^2 - x \geq 0$$.
Factor:
$$x(x - 1) \geq 0$$.
This product is nonnegative when both factors are nonnegative or both are nonpositive.
- Case 1: $$x \geq 0$$ and $$x - 1 \geq 0 \implies x \geq 1$$.
- Case 2: $$x \leq 0$$ and $$x - 1 \leq 0 \implies x \leq 0$$.
So, solution for this part is $$x \leq 0$$ or $$x \geq 1$$.
- For $$x^2 - x + 1 \leq -1$$:
$$x^2 - x + 1 + 1 \leq 0 \implies x^2 - x + 2 \leq 0$$.
5. **Analyze the quadratic $$x^2 - x + 2$$:**
Calculate discriminant:
$$\Delta = (-1)^2 - 4 \times 1 \times 2 = 1 - 8 = -7 < 0$$.
Since $$\Delta < 0$$ and leading coefficient is positive, $$x^2 - x + 2 > 0$$ for all real $$x$$.
Therefore, $$x^2 - x + 2 \leq 0$$ has no real solutions.
6. **Combine the solutions:**
The solution to the original inequality is $$x \leq 0$$ or $$x \geq 1$$.
**Final answer:**
$$\boxed{(-\infty, 0] \cup [1, \infty)}$$
