Impracticable

Impracticable describes something that cannot be done or put into practice; incapable of being done, used, or accomplished; unfeasible or impossible under the given circumstances. It often implies that the challenges are so significant, whether physical, logistical, economic, or ethical, that the intended outcome is highly unlikely or unachievable. It's a stronger term than "difficult" and suggests a definitive barrier to success, considering real-world constraints and limitations that prevent a plan from being realized.

Impracticable meaning with examples

• Building a city on the moon without extensive technological advancements and resources remains currently impracticable. The costs, environmental concerns, and logistical hurdles make the endeavor far beyond our current capabilities. The concept is exciting, but its impractical nature highlights the limitations of current space technology and resource availability.
• Despite its appealing design, the complex and expensive system proved impracticable for mass production. The assembly process was excessively time-consuming, and the specialized materials required were prohibitively costly, rendering the product non-competitive in the market. Ultimately, the design had to be scrapped.
• Creating a completely unbiased AI is almost impracticable. The algorithms will inevitably reflect the biases present in the data used for training, regardless of the steps taken to remove them. The inherent limitations of human data ensure the perpetuation of some bias, making a perfectly objective system difficult to achieve.
• Attempting to sail a large ship through a narrow canal with unusually strong currents is impracticable. The risk of capsizing, collision, and insufficient maneuverability due to the ship's size versus the canal's confines is extremely high. Navigation safety protocols would not allow the attempt to even be commenced.
