Quite the opposite actually! Imagine you encounter an optimization problem in your daily work and want to solve it algorithmically. You study the problem a little and find that it contains the knapsack problem as a sub case. Now you know the problem is NP-hard and don't need to waste time trying to solve it. Instead, you can think of ways to modify the problem or decide if you're fine with approximating the solution to some meaningful accuracy.
